So have a 20 long with six different types of plants and as it is still new I'm trying to let the plants alone so they can develop thier roots, but how do you clean the gravel of fish waste without disturbing your plants. Some of the pictures of your tanks are amazing with plants covering every surface- do the plants just absorb all the rotting fish poo or . . . I don't know. I love the plants and want to increase my collection but i'm afraid of creating too many little spaces for waste to colect. Any guidance you can provide would be supper! thanks
