Hey all,
Does anyone know of a device that will enable me to alternate the speed of several powerheads.....basically, I have three maxijet-1200's with the Sureflow 1600 impeller kits on them, I would like a device that will slow them down but not turn them off completely, then ramp them back up to full power several times an hour...
Only because i've heard these Sureflow impeller kits dont last on a wavemaker which turns the powerheads on and off.
some reason like... when the powerhead kicks back on, if the impellar starts turning in reverse it hits the reverse stop then start the correct way, BUT that the reverse stop wears the impeller down until it fails.
If there isn't a unit available commercially... has anyone made a DIY device which I could try to build???
Thanks All
