Inside an AGA reef ready overflow

The Durso-Pipe  is a EXCELLENT alternative to the stock overflow kit. Much quieter and lower cost. 

Southdown tropical play sand is next to impossible to find, but I found it here.

A pair of ball valves and quick disconnects were added between the tank and sump for fine tuning ease.

Check out the Durso web site in the links section for all of the details. Drilling the air hole on the side works great

.  

200lbs of Southdown was introduced to the tank after the water was added. It was done in that order so the sands fine particulates were able to be skimmed out.

A 20gal long was used as the Sump for this project. Some extra  supports were needed for proper weight distribution.

Filling it with water for some testing.  NO leaks...YEA!!
