system is working great, I did have to add a 1 inch pvc drain between each tote installed right at the water level I want to maintain. I had some water level rising issues due to roots blocking my 2 inch lines, and since im injecting water from the top for the water falls it would cause the tote with the obstructed lines to have to high of water levels, actually caused crown rot on a couple of plants. Now it is working great, here are some pics.How did your setup work out? Was the pump the right size? I've read many say keeping the water as dark as possible is important, did those yellow lids create any problems by letting too much light into the water?
Thanks in advance! Your setup looks solid!
