Ph changed
I have several nearly identical tanks (same type of fish, size of tanks , etc)tanks and for some reason the Ph in one tank has gone from 7.6 to 6.0 over the past two months. The other tanks remain at 7.6. The other chemical conditions have not changed. I have been doing 25% water changes every 10 days and the ph comes up but then drops down after about 3 weeks. Any ideas what might cause this. Should I slowly try to bring the ph up using chemicals?
Thanks for your time,
Tom
