Mr. hydro, I'd like to know how the 11 plant system fully drains the water from the pipes to the reservoir. The only information I know is that when the tubes are filling up with water, the bottles fill up to the same level as the overflow pipe and then from the top of the pipe back down into the reservoir. I guess my question would be, how does the remaining water below the top of the overflow pipe drain back into the reservoir when that pipe runs up and back down again?
First, would I need some sort of fill and drain fitting connected to the hose running from the
pump to the tubes?
Second, can I or should I run an air pump through this type of system?
thanx, Thanx for your knowledge
