This fuge is part of a 400g system and is set up as a display fuge. It contains 5 inches of sugar fine sand (purchased dry), and four freshly cured rocks. the water feeding this tank slowly passes through a UV sterilizer. The UV supplied water is an attempt to isolate the tank from the rest of the system as much as possible.
The Mangroves are from David, thank you.
The Stands were built to raise roots out of the water as they grow. The tie wraps are very loose and will be checked often.
