Yes, true......strong flow is relative. Trying to figure how to describe.......when I hold my hand in front of it, it moves pushes the skin on my hand. Does that make sense? The water comes from pool, into pool pump, into filter, into heater "in for cold pool water", out from heater "out for hot water from heater", into chlorine dispenser, into return vent in pool.
Bought it online, thinking it was from AquaPro but it actually was from EBay. I eventually figured out that they came from AquaPro, to Costco, to EBay. Never again!
