Steve's 20 Gallon Nano

[Coral reefer]

If you bring the two small pieces I can attach them for you.

I've used it in tank (wet) before and didn't have any issues with it other than the slight cloudiness. Your protein skimmer will go nuts so you might want to turn it off or just have it overflow into another container. No issues with the fish or the corals from using it underwater.
