The Sub Surface Air Diffuser has over 6,000 micro-pores, which creates very small bubbles. The smaller the bubbles, the more surface area the air has to come in contact with the water. This leads to a greater oxygen transfer rate and less back pressure on the system.
Pond Boss® Pond and Stone Sealant is perfect for decorating around your waterfall and starting construction on your pond. The sealant fills in gaps to ensure efficient water flow over rocks. This expandable black foam dries in minutes and fully cures in 24 hours.
