Need Kalk reference

[cyberwollf]

I know this info exisists, but I cant find it now.

After burning through 3 mj1200 impellers on a kalk reactor, im done with it (and the fact im about to start school so I wont be gone weeks at a time on business trips).  In Calfo's book he reccomends dosing your daily kalk by mixing it in a slurry and dumping it into the DT.  want to try that

I know once upon a time i saw a "max kalk per gal" in order to only raise pH an acceptable level. With all my searches tonight i cant find it with google.

second what is the "average" calcium consumption for a "mixed reef" per gallons.  I remeber seeing an average number once, but again i cant find it online with any searchs tonight.  Yes i know i need to take a few measurements and find out my specific consumption, but i need a starting point until i get that done

Thanks in advance if anyone has those links bookmarked and can post them

Don't know if this helps.

My consumption in 205G, with a packed frag tank, and DT tank, is between 20-40PPM a day. Sometimes 60PPM. As far as Kalk goes, I mix 2 TBSP per 5G, and drip it into the tank. I refill it daily, and only add Kalk when there is no more precipitate in the bottom of the container. About every 3-4 days or so. I don't have the exact figures your looking for, but I hope it helps.

I'm sure I'm alot lower than that. Mostly frags only a few colonies.

I been mixing about .5 tsp or so and dosing all once in a slurry. Not sure if that is too much or too little at one time. I swear I've seen those numbers on a Randy homles Farley article or something before.

I have seen them too. Can't find it either! Just keep an eye on your PH, ALK, and CA when you kalk. Something I have noticed since I started dosing it, coraline algae grows like CRAZY!! I have to scrap the frag tank glass every week or I can't see thru it on the 10K side.

i use about 3 table spoons a week in mine

Man!!! since you guys wouldnt do the work for me I had to actually sit down at google and read through several Randy Homles Farley (a good read for beginners, any of his articles) articles to get the info.

Adding, for example, 1/4 teaspoon to 40 gallons will raise the pH by only 0.1 to 0.2 pH units. Unless the pH is high (>8.4) before the addition, that amount is likely acceptable.

So looks like i will be adding 0.5 teaspoons of kalk slurry to my 75 daily

Still looking for my other answer.  what is the average ppm Cal used per day in a mix reef (per gallon if possible)

EDIT: I think only .5 teaspoons is pretty low.  That would be like dripping only 1/4 gal day of saturated limewater..... hmmmm
