Ok, the kH results are in. Thanks again.
Tap kH is 5, tank is only 1 though.
Is it common for there to be this big of a difference? I added 5 gallons of RO the other day, had to use it dont normally. Could this be causing the difference? My guess would be yes, but Im not a great guesser.
Thanks. Fish are acting a lil different, but as far as I can tell its nothing more than acclimation type acting.
