Underwater Warehouse offers a new membrane air diffuser assembly that features a hollow base that can be filled with sand or gravel. This eliminates the need for bricks and straps to get the diffuser to sink! Available in both a single head or dual head assemblies. A 3/4" female threaded outlet is located in the base of each diffuser. A 3/4" x 1/2" poly barbed adapter is included (non-weighted tubing).
Filters that have not had water circulating through them for the winter should be cleaned well before turning the pump back on this spring. Cleaning will remove toxins that can develop from waste breaking down in the filter in the absence of oxygen. Once your filter is up and running, seed it with beneficial bacteria.
