When I checked on the system this morning one of the plants was drooping. So I moved them back in to the Rainforest. I opened the lid to the waterfall system and, last night when I pulled the pump to get the model of it, the manifold had gotten shifted over to the one side, and was pushed forward a few inches, so the net pot of the one drooping wasn't being hit by the spray. I lined everything back up, and fastened it to the cross bar so it couldn't move again. I checked the water temp and it was 70.8 degrees, the same as my room temp. I left the pump running all morning. The plant that was drooping is now fine. After almost 4 hours of the pump running constantly I checked the water temp again. It was still 70 degrees. I noticed on the info about that pump that it's rated for continuous use, so I'm going to just let it run and keep an eye on the temps. Other than that little glitch, everything is working just fine so far.
