hi,
i have a 240l open top tank and at the moment its probably losing around 10l's a week to evaporation.
i'm wandering if i should be using RO water to top up? as if i top up with tap water or just wait and refill at next water change, wont the gh and kh steadily increase?
my tap water is moderatly hard with a kh of 8
