Tap kH/gH vs. tank kH/gH
Hey again everyone, haven't been on here in years, but started getting back into aquatics once again. I'll make this short.
I have a 20L tank with low tech plants (Anubis, java moss) black sand, lots of Malawi wood and 2 adult axolotls. The filter is a HOB with regular media. Low light and nothing is dosed.
I'm upgrading to a 30 so the axos have more room. Going to have more plants, canister filter with seachem matrix and foam. Lighting will go up to 55w t-5. Going to use ADA or Eco-complete and am planning to not dose.
Anyway, the current tank had major pH swings during cycling and now the pH is still too low. I'm assuming its due to the lack of buff in the kH. Just tested both and got TAP WATER: kH 4 and gH 5. TANK WATER: kH 0-1 and gH 12-14!
I'm kind do confused to what's going on here, but I need to get kH up to keep the pH ideally between 7-8 (it's dropping to 6 now). GH looks good as for as the tank water is. Any idea why such a water change is occurring from tap to tank? Any and all advice is welcome.
P.S. I have cc, alk buffer, Epsom salt that I can use.
