+1. While aquatic plants prefer ammonia they will also uptake nitrate. If you have so many plants that they starve your bb you don't need to worry about your bio bacteria. If you get yourself a ton of aquatic plants your nitrates will be sucked dry. I used to have a ten gallon tank with a dwarf puffer, and I allowed my water wisteria to go crazy inside the tank and I never had any readings on any of my test kits. I actually thought my test kits were broken until I started my planted fish tank and was adding large amounts of nitrate to feed my plants. I would get an aquatic plant that grows quickly, the faster a plant grows the more nutrients it uptakes.
