How to recirculate a 4 bucket waterfarm system with a res and controller?

[The White Snoop]

I went the easy way out and elevated the waterfarms 2 feet. The drain on the waterfarm is about 1 inch from the bottom of the bucket so it did not have much fluid in the bucket.
On the inside of the bucket I connected an elbow with ~4 inches of hose to the drain plug. Now each bucket holds about 4-5 inches of fluid.

I put another plastic tube into the waterfarm exactly like the current one. From the main res, water flows from a water pump through a 1/4" hose which is threaded through this plastic pipe. A seperate airline with an air stone attached to it is also threaded through the same tube.

Sounds great! :thumbsup:

Would love to see a pic
