This is the build that I was going to tear down this Thanksgiving weekend. The upgrade from the 120g to the 180g went great..... for a month... then various problems that lost all the corals. It has been in stand-by mode for 2 years now. Fish are doing great, but water quality isn't even ready to try corals again. I have many theories on the problems from the upgrade, but I also had alot of work and side-issues during this time, so I didn't get to post any of it. OR get to 'fix' any of it. After the corals died, I kinda gave up on it.
The coast-to-coast overflow system is working great. The BeanAnimal overflow syphon is working great, and silently. The two big problems were #1 loss of heat - the temp dropped more than I wanted with all the extra water/air interaction, and I'm pretty sure my cheap digital therm was off. The heaters blew a circuit and I have no idea how long they were off. The 2nd problem appears to have been my older rock. It was storing up some nutrients and when I switched tanks, I used ALL my 120 water, but needed like 100 gallons of new water. This probably caused the nutrients to come out of my rocks, causing the hair algae outbreak also leading to the demise of the few corals I had. The 3rd problem might have been the lower flow through my above-the-tank 30 gallon refugium. It has tons of pods in it, providing a great food source. But I had to lower the flow due to the new tank plumbing. The 4th problem may be lack of wave action. I have great flow in the tank, but my vortech died, and it was only source of variability... My 5th problem... well, you get the idea...
So I have 2 new projects. First is a simple, unbelievably simple Up-Flow Algae Scrubber. I set it up in 5 minutes. I will take some pics, but it is easily running in my refugium, taking the place of my non-growing chaeto macro algae. 2nd project is going to be a regular waterfall Algae Scrubber in the main sump. This is almost done, but had to clean up the basement work area for guests today. The theory being that hair algae grown on a mat will absorb extra nutrients faster than anything else. After seeing this first hand, with water that tested perfect, I can see how this may well help significantly.
I will post picks tomorrow, time to make my family's sweet potatoes - basically caramel with some orange squash in it....
