I'm in complete agreement. After recently learning that pH neutralizers contain phosphate buffers, I've decided to discontinue using my Seachem Neutral Regulator. My tap pH runs fairly high (7.8-8.0), so I keep driftwood in one tank to lower it.Gunnie said:Bogwood or any other driftwood deemed safe for your tank would be a natural way to reduce your ph level. I'm with Butterfly. I would not buy any chemicals to lower your ph. The bogwood would be an acceptable way to do it.
