Just passing this along.

I have been told by someone with many years experience in Hydro that the Rubbermaid stuff is made from the wrong material to survive constant contact with the nutrient solutions. By about the second or third cycle they will crack and leak spilling everything all over the place. Probably OK for water-only useage.

Just a tip. Also the light getting into the resevior will cause algea to grow so you have to shield it from any light.
