GCTek AlphaOne Pond Filters

AlphaONE Filters utilize the AquaSwirl internal Vortex spinning design that spins heavier solids to the center of the bottom of the vessel. AlphaONE filters also feature the AlphaONE Life Support System, known as "ALISS", which keeps beneficial bacteria alive indefinitely during times of medical shutdowns, pumps failures, etc. The 2" Clear Union Spring Check Valve located right under the blower provides maximum flow and has built-in unions. If you should ever have to replace the spring check valve, it is no big deal. Just unscrew the top and bottom of the valve, remove the valve body, replace with a new body and re-hand tighten the two unions. Total repair time is under 2 minutes!
