I retested both baking soda and equilibrium seperate, and they both raise TDS. I only treated the water change amount, not the whole entire tank. Well, I did another water change and brought it back down to 250 TDS. That's good for now, it has 5 KH and 5 GH, is that good enough for cherries? I'm also returning the equilibrium, it didn't mention raising TDS, that's my reason.
