what's the pH for the water out of your faucet? i'm surprised by the high pH
Out of the faucet its about a 7.2-7.4.
I'm surprised too. My tank has always been very stable.

Go get freshwater buffer it will work fast to get it back up
Adding tabs or other additives will raise your TDS which has its own set of problems. What is in your substrate? If you can get hold of R/O water it will help a lot. Maybe go to a bare bottom tank and start from there. Try a few drops of white vinegar added to your water changes. Remember that white vinegar has a PH in the 3s so go slowly. Treat the water during your Water changes....not the tank. Lower the PH slowly to prevent shock. White vinegar is cheap usually around $2.50 per gallon, and much cheaper than prepared solutions. I suggest starting over if you can. The problem is somewhere in your tank.
How long has your tank been up and running? is your tank still cycling? A high PH with even a small amount of amonia is a death nail to fish. A liquid CO2 can also help
Hmmmmm! that is very preplexing. How old is your filter carbon etc. If it is more that 3-4 weeks old, it is exhausted and could be leaching toxins back into your tank. If you are using preparations to lower PH as well as running charcoal, the charcoal could be stunting your progress by counteracting all that you are doing......try removing carbon during your next WC, use white vinegar and measure over several days. be sure to add O2 (airstones) to help the BB colony
