I'm all set up with gravel and everything but I have an inconsistent bell siphon. It will work usually three or 4 times in a row but then it will just reach an equilibrium low in the grow bed. I have already massively diverted the water coming from the pump. Its to the point that it takes about 24 mins to fill the grow bed and 3 to empty it. I'm already not going to be pushing through a whole lot of water. grow bed is about a hundred gallons total and my fish tank is something like 150. Has anyone dealt with anything like this before. I have only read about peoples siphons working or not working. Not working 75-80 percent of the time.
