I have tanks with driftwood and they are usually the ones with this problem. I had one tank that the pH was at 2.00 with these symptoms. The weird part is the water around here (KC) is very hard and a very high pH. This was not RO water. I believe the driftwood is the culprit. Good luck with yours! Michael
