Shauna Posted June 25, 2021 Share Posted June 25, 2021 29 gal that has been set up for 10 months, ph has started drop and is currently at 6.4 My tap ph is 6.8 and basically non-existant KH and GH. I didn't realize when I set up my tank, that I would need a ph buffer. I add Seachem Equilibrium with water changes and wondershells every few months along with easy green and my plants are pretty happy. Just worried about the fish if ph continues to drop. I should have started with crushed coral mixed with my substrate. I also have 2 large pieces of mopani wood that probably contribute to the ph dropping. I really don't want to just dump crushed coral in with my brown gravel. Are there other rocks that will buffer ph? 2 Link to comment Share on other sites More sharing options...
