Review on AQQA Submersible Water Pump with Controller - Variable Frequency Return Pump for Marine Freshwater, Fish Tanks, Aquariums, Fountains, Hydroponic Ponds - 800-3200 GPH by Jennifer Madrid

I received this pump on March 31st. It works with a timer and only works twice a day for 15 minutes each time. It has almost no time to work. He died on July 15th. Waiting for an answer, we'll see what happens next. Actually the problem is that the pump shuts off when the water level drops about 2 inches above the pump. When I bought the pump I thought the pump would turn off when the pump started sucking air, but it turned off long before that. I decided to replace it with a Danner pump. I have a Danner pump on another hydroponic system that has run for years with no problems. I asked and received no response from AQQA. They could contact me and explain what the problem was when I explained my problem but I guess they really don't care.
