Title: Homemade CO2 Scrubber
Post by: SweetReefOH on August 16, 2017, 18:19:21
Well since you guys talked me into an apex, I now see all the faults with my chemistry lol. I never knew I had a pH problem until I got the apex. It was getting down to 7.70 occasionally. I keep the house closed up pretty much all year except for a few weeks in spring and fall. So, obviously I have a CO2 problem that I never knew about. So check out my CO2 Scrubber courtesy of Dave and Busters 3/8" straw!

Are you running your skimmer intake through this?  Let us know if it helps.  Ive read where it can be expensive to run these.

Yes. I bought 3' of soft 3/8" tubing for $8 and I bought 9lbs of the soda lime for $50. Both from BRS. I know there's cheaper soda lime out there but the BRS claims to have a coating on it that makes it last longer. I will post some numbers tonight when I get home. But so far it definitely helped overnight. The pH hasn't dropped below 8.0 and it's normally way below 8 when I get up.

Post by: lazylivin on August 17, 2017, 10:01:30
Following as well. My interest is if two part consumption changes indicating an increase in growth speed. Many years ago I connected a powerful air pump outside, pumping air into tank sump. I had an immediate increase in PH. Within 15 minutes. Ran it for 6 months. In the end I so no difference in coral health or color so I pulled it out. However I did not have automated dosing at that time to identify if there was enhanced growth indicated by increased 2 part consumption. If there is benefits in calcification speed it would be seen immediately. Within in days of connecting assuming the CO2 scrubber is working and increased PH.
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 17, 2017, 11:29:58
Brian, I did some testing prior to deciding on the Scrubber. I stabilized my dosing until I had three days of less than 3 points swing in ppm on the Hanna alk checker. I then left the windows open for 3 days. Immediately the next day alk consumption knocked down the ppm by 8 ppm. So I started dosing an additional 5 mL. I then closed the house up like normal and the pH dropped. The ppm on the alk went up 9 points. Signaling less consumption. At this point I have left the dosing regimen the same and I will test again when I get home. I am expecting to see the alk back to where it was when I had the windows open. I know this is far from scientific, but it is good enough for me. For what it's worth, I didn't notice a change in Calc, but I manually test that with the Red Sea kit.

Have you used the same vials and retested it over and over again? For example fill one with your saltwater and the other vial with your saltwater and reagent. Then repeat test 4-5 times in a row back to back. I ask so we can see the margin of error on your meter
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 17, 2017, 11:42:20
I understand there are margins of error. When I have 2-3 days in a row where it is within 1-2 points of the day before, I consider that consistent and accurate. I do use the same vial, cleaned the same way with the 10mL tag facing me, every time I test
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 17, 2017, 11:45:05
From what BRS's video on pH and CO2 scrubbers said, its a guaranteed fact that having your pH between 8.2-8.3 increases coral skeletal growth significantly. Which creates another problem if your pH drops. You'll be overdosing your tank....

I find this subject interesting and would like to get more in depth with it. It would be nice to know the percent of calcification increase associated with the PH level. For example if a tank required 100ML Calcium and Soda Ash per day to maintain alkalinity level of 9.5 and Calcium level of 400 at a average daily PH of 7.8. Would a increase in average PH to 8.2 equate to a dose of 120ML to maintain ALK/CAL. If yes we could say it is a 20% increase. We could learn this but would need a KH Monitor in the mix as well where we can get various alk levels throughout the day that would also have a PH level at the same time. When the Apex one comes out I will definitely get it. For now the method you are doing, testing each day and matching it to the average PH data points over the day we should be able to draw some conclusions.

I wonder at what average daily PH does it no longer benefit? Could a PH of 8.5 be better then 8.3? Could the same be achieved by keeping alkalinity higher? How about lighting. What if we increased that? So much to learn in this space. With the dawn of Alk monitors and alk consumption being tied to growth I think we will learn a whole lot over the next few years and will see some pretty incredible reef tanks as a result

Post by: SweetReefOH on August 17, 2017, 14:57:30
I whole heartedly agree with you. I love the numbers and tinkering with things after reading and hypothesising and testing it on my system. Albeit, your brain is working a lot harder than mine! I tend to overlook a lot of the little things you catch. I will say, the corals just looked a lot happier with more polyp extension when I was keeping the window open. But living in Ohio, that is not feasible for me year round.
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 17, 2017, 17:16:28
Ok Brian, I did your test. I think you need a new Hanna Checker lol. I tested it 7 times. Turning it off after each. Every single test was 173.
Also, as I suspected, the alk has dropped from 9.96 when the house was shut, to 9.68 with the CO2 Scrubber. It is obviously consuming more alk at a higher pH. The pH is up to 8.18 at the moment and I still have a 2.5 hour photoperiod left. Hoping to reach over 8.2. The Scrubber is definitely working.
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 17, 2017, 20:12:16
Well I topped out at 8.21. It's actually holding steady during my light ramp down. I think I will have a head start on tomorrow if the pH stays a little higher than what it dropped to last night. Fingers crossed. I will test the alk again at the same time tomorrow to see if there was any additional consumption. I'm attaching a simple photo markup of my pH over the last few days under what circumstances. (https://uploads.tapatalk-cdn.com/20170818/599f71242808765479cd4a3264c92750.png)

Joel, sorry I didn't respond earlier. Just noticed your question. I have a 75g with a 30g sump. I only have about 63-67g of water due to all my rock in the display and sump. So far, no blue beads yet.
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 18, 2017, 17:26:24
New results...
I know I am being less than scientific because I'm making adjustments as I see results. But, today I came home after approximately 48 hours of the Scrubber being online and again I see a drop of .15 in my dKh and 20 ppm drop in my calcium. I am going to bump the dosing up another 5 mL on each. My conclusion at this point is you don't even have to maintain a pH of 8.2 to start noticing more consumption. I now have a peak of 8.2 that only holds for 15 minutes before it starts dropping because of my light schedule. Previously, my peak was about 8.05. Take that for what you will, but I am definitely keeping the Scrubber online for whatever little extra growth I'll be rewarded with.
Title: Re: Homemade CO2 Scrubber
Post by: lazylivin on August 18, 2017, 23:14:38
What was your daily ml of dosing and what is it now with the bump up?
Title: Re: Homemade CO2 Scrubber
Post by: CoralBeauties on August 18, 2017, 23:40:49
I would have to question if the higher ph would be what is effecting the alk level decrease?  I would be surprised if the corals would start growing that fast within just a couple of days to have affected a drop in alk.  From everything I have seen in this hobby good things are slow to happen and bad things can happen in minutes. 
How do you post your apex charts?  I would like to share mine since I have opened the window in my sump room.

What was your daily ml of dosing and what is it now with the bump up?
Prior to doing any of the open window/Scrubber testing I was dosing 50mL alk per day and 30mL Calc. It was stable and consistent. I am now up to 60mL alk and 50mL Calc. However, it's too soon to say that it is stable at these levels. I'd like to see what the tests are over the next week.

It may not be the pH that is directly affecting it but the byproduct of more oxygen in the water column. With all other things the same in my setup, it's the only conclusion that makes sense. I believe they mention that in the BRS video. The higher pH instantly triggers greater consumption during the full power period of photosynthesis.
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 19, 2017, 11:17:15
Here is the link to the video I found when researching low pH. This has all the scientific evidence of the hydrogen exchange within the corals and how a higher pH makes it easier for the corals to grow. https://youtu.be/t69huBU8xyM
Title: Re: Homemade CO2 Scrubber
Post by: CoralBeauties on August 19, 2017, 23:25:31
It surprises me how fast the change in ph will effect the alk levels.  I have left my basement window open in my sump room for the past week and my ph hasnt dropped below 7.8 with daytime highs at 8.2-8.3.  I tested my alk tonight and it has plummeted clear down to 6.9  I had several frags of red dragon stn this week and that explains why.  come cooler weather I will probably have to look into a scrubber and maybe try and control it with a solenoid valve like what was done in the posted video.

I hope your frags find their way back.

My pH hasn't dropped below 7.8 either but I barely get over 8.2. So your doing great at 8.3. Do you dose heavy during the day? I've got my alk dose shutting off from 9am-12pm and dose Calc in that window.

Initially I was going to do the valve as well but knowing how often the house is completely shut, I decided on the BRS media to see how long it would last first.

After seeing your tank and you pH levels vs. mine, I had to look into it....
Title: Re: Homemade CO2 Scrubber
Post by: CoralBeauties on August 20, 2017, 09:30:43
Does anyone know if co2 is a heavy gas and settles into the lower places of a home like your basement?  I have had my skimmer intake pulling air from outside for along time with no ph change.  I have a weeks worth of charting with the window open so now I will try closing the window and see what my chart will look like.
Jeff
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 20, 2017, 09:44:28
That was a suggestion I read somewhere in my research. To run your skimmer line to the ceiling because CO2 is heavier and concentrates low.
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 20, 2017, 09:47:09
Also, be sure to adjust your dosing accordingly. I test every day just the see what the water chemistry is doing. Especially when I'm experimenting!
Title: Re: Homemade CO2 Scrubber
Post by: Agame43 on August 20, 2017, 10:22:21

  Jesse, you are kinda right, I got you interested in it through our conversation. I got thinking last night, why did I dig into it back then, well I just wanted to "lessen the 24hr pH swing" if you will. My pH would swing from 7.8/7.9 at night up to about 8.2 during the day, so I dug into it a bit and found this method of using the outside air. By adding the new air to my skimmer my daily swing lessened and my average pH cycle shifted to the higher side as well. My daily cycle now is about 8.17 to 8.35 or so, sometimes 8.45 on a good day. Interesting information.
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 20, 2017, 12:34:14
Rick, your numbers are fantastic and the beauty of your tank is a result of that, in my opinion. I am thankful to have seen it and that we discussed the pH. It pushed me into research.

I'm not sure about its weight, but if you have a CO2 problem inside then surface agitation and fans etc will drive down ph worse from what I've read.  If you do implement a scrubber I would scrub the outside air so the media lasts longer.  I'm still planning my display, but I'm really considering using two skimmers rather than one to help pull in as much outside air as possible when the time comes
Title: Re: Homemade CO2 Scrubber
Post by: SweetReefOH on August 20, 2017, 19:38:33
Joel, that's a fantastic idea and would probably work even better. The reason I am only doing the Scrubber is because I really don't want to drill my house or window sill for the outside air. Just adding the Scrubber alone has made a massive difference in pH, polyp extension and alk and Calc consumption for me and I am good with that.
Title: Re: Homemade CO2 Scrubber
Post by: CoralBeauties on August 21, 2017, 21:55:23
I closed my basement window last night and today my daily high ph compared to yesterday was .12 lower.  I will leave the window closed for a couple more days to confirm the lower ph.  Jesse let us know how long you get out of the co2 media?  The brs video says they are using $7 worth of media a week.

Ok so this is where I am at now. I've had to bump my alk up a total of 40mL and my Calc up 60mL since I started this experiment. That is double what my consumption was before starting this journey. What I have also noticed is that once the media become spent at the bottom of the "reactor", I've only got half the reactor usable and I believe it's allowing CO2 through and into the skimmer. It has only been a week. So, at this pace it would be $7-$10 to maintain the BRS media. That is a little steep. Also, since the pH is slowly creeping down, I am going to have to slowly bring my dosing down in order to use up all the media. This is unfortunate and too much micro-managing. So my solution is this.... I just purchased 2 of the BRS scrubbers/reactors. I am going to fill one canister, initially, and then wait for it to start changing color. Once the color change starts, I am going to daisy chain the second one to it with new media. Keeping the partially spent reactor at the front of the air intake. So, any CO2 that gets past the partially spent media will then go thru the fresh media, eliminating all CO2. And then weekly, if necessary, I will discard the spent media, move the partially spent media to the front and fill and reattach the second reactor. This should eliminate the pH swing I am getting now. I also don't believe the expensive BRS media is any better than any other soda lime cuz it only lasted a week. So next time I am going to get the $27 media from another vendor and see how long it lasts.

I had to open the window tonight.  The tank had a low of 7.6 this mourning and a high of 7.96  I clearly have a co2 problem in the basement.  i will have to do some research on ventilation systems for basements.  I would like to not have to go the route of doing a co2 scrubber if I dont need to.

I've been keeping my window open waiting for the new scrubber containers. My numbers are close to that, but you still have me beat. On a side note my consumption has went from 50mL soda ash to 110mL to maintain my alk over 9.0 since I started the pH experiment!

I thought I would share how I was able to get rid of the co2 that was in my basement. I had a small blower at work that wasn't being used so I put it to good use.  I believe it was for a radon system. I installed it down on the floor and ran some pipe up and out my basement window.  I cut a piece of wood the same size of the window and ran the pipe outside. Since running the fan my pH has not dropped below 7.9 and an average high of 8.25.  Before the fan I was getting lows of 7.69 and highs about 7.9 This has been wonderful for my tank and has helped out with basement odor.

 Thanks for sharing Jeff that's a pretty cool solution you have there. I wonder if  you ran the fan at window level not having the extension tube would you get similar results?  Also would you get better results if you brought air in from outside?  Would there be any drawback to that?
Title: Re: Homemade CO2 Scrubber
Post by: CoralBeauties on September 17, 2017, 23:21:32
co2 is heavier then the air in your home so it is needed to have the fan at floor level or have the fan in the window with the intake plumbed to the floor.  I didnt want to deal with blowing cold winter air into the house and I think co2 wise you would want the fan to blow it outside the home.  There are several systems that work this way for removal of excess humidity, even claim to reduce the need for dehumidifiers.  I cant tell about the humidity claim but for co2 and the occasional musty basement smell it has really helped. 
  Like reeferntraining I have also noticed a fairly large drop in alk and have had to increase my supplementation.

co2 levels are differemt when talking 1,000 of feet or miles however in our homes level of co2 from height of your window to floor is not likely a difference great enough to impact the results. I am thinking you could have your fan at window and still get the same postive results. Might be worth a try if that piping gets in your way.

So you feel a bathroom vent fan on the ceiling would do the same?

I think so but not sure. If it did then that would be ideal in my situation.
I was also considering trying to run skimmer air intake outside.

It would probably pull out some humidity too.  Have heard of people using bathroom fans for that.  I'm running a dehumidifier like all the time which ain't cheap.  Might try to rig something too.

I have been running the fan 24/7 so far but put it on a timer last night to run 12 hours from 9pm to 9am.  I'll see if there is any change in the ph of the tank with the reduced run time.

I actually thought about that myself. However, my tank room is on the north side of the house, on the lower level, so it gets no sunlight at all...

I’m glad I ran across this thread! I’ve been battling low ph because of high levels of CO2, but didnt know the best way to correct it. I happened to have a spare DI canaster so all i needed was the CO2 remover from BRS. I’ve had it installed for 3 days now and have watched my ph rise each day.

Glad to be part of this community.

Love the scrubbers guys.

For anyone whose run the airline outside, when it's really cold or hot out, does it monkey with your tank temperature much?  I want to do it, but I've always wondered this. Anyone know?

I’m curious of this as well. I almost ran the tube outside but was afraid of possible temp swings. I still might do it, just to try it out.

Since it’s been a while since we were discussing this, Has anyone experienced temp problems with running their skimmer intake outside in this weather?

I’m planning on running mine outside today. I’m going to run it through the wall and down to the basement so it’s going to be a bit of a task though. I will post if there seems to be any temp changes.
