Re: Ro/di Water
If you plan on just using RO water for your tank, then I think it would be best to purchase some sort of nutrient source to add back into your tank. RO is stripped of any nutrients that help support your healthy fish. For instance, when I do a w/c I have my RO water source ready to add back into my tank, and before I add the water back into the tank, I add my nutrient source into my tubs that are holding the water and give it about 30 seconds to dissolve into the water and then add it into the tank. Add only what the bottle calls for. If you need a specific brand, I use KENT cichlid liquid chemistry mix. Its a great source of providing natural water chemistry to african cichlids and other rift lake fish. KENT also makes a liquid chemistry mix for community fish.
