I'll be switching to RODI
water for my 55g Apistogramma tank soon. I've read that RODI
water lacks the trace minerals and such that they need, but I don't know what the best stuff to use to add them to the tank is. I've done some research, but I don't know which I need. It's a planted tank, fairly simple and low tech. Vallisneria, java moss, moss balls, water lettuce, and duckweed. It has a sponge filter, rated for a 75g, as it's only filtration method. I've got a dozen Glowlight tetras, four BN plecos with only one male, and a pair of young Apistogramma, with a confirmed female. What would be the best trace minerals to add to it? I've also got some Indian Almond Leaves for the tank as well, and there's driftwood in the tank.
