I'll start testing everything now, and post when I get results for everything.
Yes, I am using both high and low pH API brand testing kits. It's liquid, too. I am not injecting CO2, and all tanks are filtered and cycled. Tap water is 7.4, and all the tanks are about 9. The water source is well water, from my tap. I dohave a water softening unit on the house, is that bad?
I haven't tested the hardness KH/GH, I only have tests for ammonia, nitrite, nitrate, and both high/low pH. Should I go buy a KH/GH test? I'm assuming they're high since I have well water.
My Water Parameters Are:
Tank One-0,0,20
Tank Two-0,0,10
Tank Three-0,0,15ish
And yes, the only additives used are the dechlorinators. Except one tank is quarantining my Betta who is getting an aquarium salt treatment. There's 1TBS of aquarium salt, and it's in 5 gallons of water. Oh, and all tanks are heated to ~79*F.
Thank you so much!
