Rdwc

First RDWC after a few grows in DWC found just 2 leaks yesterday in a 4 position + reservoir rdwc in a 4'x4'x80 tent with a 315w CMH light using 4 7.5 gallon totes and pvc and a 20 gallon reservoir outside side the tent was going to add a waterfall but decided to just run return line straight back to the reservoir for now, water level is controlled by the S shape on the pvc coming out of a bottom vent hole using some 2x4s cut to size to raise the the totes and/or the reservoir my water level is running about 1 to 2 inchs below the netpots using a 650 Gph inline pump water it has a good flow to it my reservoir is 8 ft from the tent. Using a microbubble air stone in each pot and reservoir.
Should be done today took the 2 bulkheads that were leaking and replaced the washers and added silicone to the base that fits outside the hole will refill and recheck for leaks later today and will get some pictures to post.
Thank you.

So no waterfall? Just a current to circulate water around? If you cap and drill the feed lines inside your 7.5 gal totes it would create the waterfall and you could do away with the airstones. From what I heard airstones add heat.
