It is a community freshwater tank, mostly rasbora and two clown loaches, 30 gallon tank. Tap water comes out around 8.0, eventually dropping to around 6.0 without stabilizer. The stabilizer keeps the drop to around 7.0.
I have mixed feelings about using PH stabilzers as well, but for whatever reason got into the routine of weaving it in once every month or so. I also use a buffer in another tank I have with cichlids. Ive been doing it for years with no problems, though, as you say, maybe not necessary.
If anyone knows what the measuring translation would be, Id appreciate it.
Thanks, again.
