Very Satisfied
Very pleased with the construction of the parts. Took me a minute to figure out my grow bed was too small for the size of water pump, but now that I have that corrected in my jumbo sized kitty litter pan with a 50/80gph fountain pump I can fill 2in of water into the pan in 2mins and the bell siphon drains back into the fish aquarium in 90secs. I am completely comfortable leaving this unattended, and it flows 24x7.  Notice for anyone doing this indoors near your living area, the water flow noise of dumping then the vacuum gurgling, as the suction flow stops, can be very distracting while watching TV or trying to sleep.  Otherwise I am very happy with this as my first attempt at recirculating water for plants.
