CART. 500 GPH Aerator Pump for Ponds, Aquariums & Hydroponics - High Efficiency Oxygenation System for Fish Tanks, Water Gardens & Indoor Plants

Needed to replace my aerator pump and I like the easy swap heads on these and use them for my bilge pumps as well. The old aerator screwed onto a 3/4in valve with standard garden hose thread (11.4 threads per inch) but this uses 14 threads per inch so they are incompatible. The screw portion does however fit snugly into a 1in pvc pipe so gluing it in that with a garden hose connector on the end fixed it up nicely.
