Planed only tank with no substrate fertilizer
I have a tub I'm using specifically to grow floating plants. Rather than dry dose or use liquid fertilizer daily, do you think it would suffice to just dump some osmocote plus into the water and allow it to just constantly fertilize the water column? The tub is just floating plants and nothing else, no substrate or anything. I do have a circulation pump flowing at the bottom to stir the fertilizer.
