ATO Reservoir

An acrylic reservoir holds Top-Off water near the sump, limiting how much total water can be added to the reef in a single session. This protects your livestock from dangerous salinity swings. Use an automatic top off system with this reservoir to replenish what evaporates daily.

8" wide x 12" deep x 20" tall holds 8-gallons. Cover lid is made of polycarbonate to avoid warping, drilled for 3/8" tubing. Previous versions (see other pictures) were made with a hinged lid, but the newer version is stronger with better access to refill container. The notch in the access port is designed for the top off pump's power cord. 

Made with 1/4" acrylic.
