When you lawn turns yellow, the recommendation is to add nitrogen rich
fertilizer. Similarly, aquatic plants can't live on trace elements alone!
They also need the macro nutrients- N, P, K, S, Ca, etc. Unless you are
feeding fishes in this container (to provide N and other nutrients), you
should be looking at a more complete fertilizer.
