My water sprite and Moneywort are metling. I don't give any fertilizers and I think that's the reason why. My ph is 7.4 and I have a full spectrum 16W light. Te new shoots of the water sprite are white, so does that mean I need iron? What is a good fertilizer other than Easy green all in one? The current plants are Moneywort, Water sprite, Dwarf Aquarium Lily, El Nino Fern, and Anubias. What other plants are good for my water?
