Hi Jason I designed and prefebricated both the columns and all the all the stuff you see in my picks. I have already started selling custom systems for other breeders and hobby guys. Thw D/I columns you see are made of clear PVC and are $1,500 each. I have experimented with a few different manufacturers of resin and presently I am using a great Nitrate resin from Purolite. (they have a few diferent offerings) My Cation Resin is a colur indicated resin and turns from purple to white when exhausted.Originally Posted by Jason
The air source for the tower is just the excess air from my air pump to the hatchery. it is made with an in and out and the out gets vent through a 3/8's hose to the outside through the wall.
