I am having problem with my alkalinity being too low in my 210 gallon. Here are my test results
Nitrates 1 ppm
Phosphates, ammonia, nitrites 0
Ph 8 (with the lights off)
I dosed yesterday with BRS soda ash. According to their calculator 5 oz should have brought it up 1 dkh
. But it only raised it .3 dkh
. Should I continue to slowly raise it? I am afraid of throwing everything else out of whack if I continue. Also this tank has new substrate (about 6 weeks old). It is caribsea aragonite seaflor special grade reef sand. Is this affecting my test results?
