Baroose_Le Posted September 2, 2015 Share Posted September 2, 2015 I set up my little 3 gallon PiCo tank a few months ago and haven't done much other than let it cycle, add a CUC and a couple tiny frags of zoas, pulsing xenia and a tiny chunk of pocilopora from my 150 just because. I feed my CUC a bit and have been changing out about 1 gallon of water every week and have some chemipure elite in the back chamber (maybe 2 oz). I finally have the time to devote more energy to this tank and have began testing calcium and alkalinity to see where I am at . I would expect almost no fluctuations in these parameters since there is barely any livestock but strangely, my alk usually drops several points every day. The first time I tested, it was 5.5 (!) and after bringing it up to 8.5 or so, rapidly drops about 2 points every day. Basically, I am having to dose my alk daily and I don't have anything in the tank yet! Any ideas? I have heard chemipure can drop dKh but this much? Thanks in advance Link to comment
seabass Posted September 3, 2015 Share Posted September 3, 2015 Yeah the GFO in ChemiPure Elite can cause alkalinity drops. Maybe the small water volume makes this drop even more dramatic. Link to comment
