GARF'S SUMMER REEFS = bubbles and sun

This image shows how we reinforce the filter. It is not necessary to use two light grids because the screen is wrapped around the entire filter. We do not plug the pipes in the frame so they will fill with water, and that sinks the filter when it is placed in the tank.

We will continue to report on this low cost and energy saving green house. Next week our new pipe bender should arrive. This bender makes the pipes used as the top rail on chain link fences into a bent frame for the green house.
