I have a sealife pro 200 sump system. I have been scratching my head over how to effectively change over from bio balls which it came with to a deep sand bed which I would rather have in the sump area then in my display tank area. I am really nevous about removing my bio balls but the high nitrate thing is really starting to annoy me and my corals. So .. here is my plan put a rubber maid container where the bio balls now reside and fill the container with sand leaving enouch room for the water to spill over and continue on to my return so that I would have a waterfall effect. Forgive my drawling but at least it'll give you idea of what I am thinking. Any one ever done anyting like this before or thoughts on if it'll work and do what I want it to would be great!! or alternitives TIA
