Ok, I sure that everyone is getting sick of my pH problems, but I am at the stage of pulling my hair out over this, so please help. My tap water has a pH of 7.6 which is fine for my guppies, but does not seem to be good for my betta. He eats fine, does not clamp his fins, and is always happy to see me. He does not however blow bubble nests like he did when I got him (before the water aged and the pH raised). I am guessing that he is fairly old. I got him from a horrible little pet store cup and he has very large fins, causing me to think that he must be getting there in age. He had fin rot and I finally managed to treat that. I tried to chemically lower the pH to no avail. Then I got some driftwood. The small piece in his tank has not done the trick as of yet, but the larger piece that I put in a test 5 gallon bucket, caused the pH to become acidic. I was going to put this piece in my 15 gallon that just finished cycling (my betta will be moved once my plants come in along with a few buddies), but I am worried that it will lower the pH too much, and then when I do water changes I will shock my fish. Does anyone else have driftwood in their tank that could offer any advice on this? Also, most of what I read says that a betta should do fine in a pH of 7.6. Could it just be that he is old? Do your old bettas still blow bubble nests? Should I still put the driftwood in the 15 gallon, how would I get the pH to be stable if I do this? I know that a stable pH is very important, so I have left the pH at 7.6 for several weeks now and still no bubble nests. Any advice would be GREATLY appreciated, as I just don't know what to do at this point. Should I put a ro unit on my christmas list? Thanks.
