I'm researching the do's and don'ts while my tank is empty for the next 9 weeks (treating Ich in hospital tank) - one of which is to not add water from the LFS to the system (makes sense). This is how we've always gotten our water, so my question is: where do I get water I can add and guarantee there's no Ich in it?
Same LFS offers RO/DI freshwater... Should I get that and mix salt?
