Hi all, looking for some advice on my water change regime. I'm currently using about 90% RO water for my water changes because I have soft water fish (rummynose and Denison barbs). I have learned from this forum that plants are quite adaptable so am not worried about using my tap water. Anyway, my tank water at the end of my 6 day EI dosing is TDS 400. My tapwater is 375 TDS. Would it be okay to gradually cut down my RO water ratio to 0%. Will my fish and plants be okay and do I nned to adjust my dosing, currently 75mls of micro and macro ferts on alternative days?
