Remember drill the holes as small as you can and not tooo many. It will be a testing kind of thing. You may want to try your pump first as it is alot of volume to push.

Also, the oxy in the water is made when the bubble pops at the surface of the water. Not when the bubble is just raising to the top. The little splash at the top is when the magic happens.

Six Plant Rubbermaid DWC Hello everyone, I currently have a 3ft X 2ft X 6in tray that I use for ebb and flow with a 14 gallon reservoir underneath it. I built the system with rubbermaid containers, and did not put much consideration into complete drainage. The fill/drain fittings are right in the middle, causing a small layer of water to remain for most of the day, every day. In the future i will place the fittings on one end of the tray, and have the other end slightly elevated, to force all water to drain to one Rating: 5
