Thanks again for letting me pick your brain. I find it interesting that the Gast 0523 is rated at 1/4 HP and uses 190 watts of power as opposed to the diaphragm pump (the Eco Plus 7) which uses 280 watts (both at 120 volts). Seems like the Gast pump will not only pump more air at depth, but use less power to do it. Making it cheaper to run and with better results.
The Gast pump also says 127 L/m while the Eco Plus says 200 L/m. So what it boils down to is one needs to see the pump curve. So I have, once again, learned something new. Thanks for taking the time to educate me!
By the way, that little pump produced a boil on two diffusers all last summer and fall, and all spring until now. So it is no slouch.
