My PH has dropped from 8.4 to 8.0 and I think it even went lower than that over night because I lossed a few fish because of it. What is the best way to raise my PH? I have been using seachem products to raise my PH. I have all there products except Reef Advantage which I plan on picking up today. Nothing that used to work seems to be raising it at the moment so that tells me that something else could be wrong. I am trying to use products that does not raise my akalinity because it was high before this happend. I did a few water changes with in a 7 day period trying to correct my Akalinity problem so that could be the problem. Please help me with this issue.
