I am currently looking at getting 2 - #4's for my 90. Marine Ddepot claims that these should NOT be used with a wave maker. Dang... that is what I wanted to do. Has anybody tried using these with a variable power source, i.e changing the phase of the current feeding them to cause the impeller to speed up/slow down? (Think motor speed controler, not voltage).
What about turning them off for feeding and nighty-night mode?
Any inexpensive sources out there?
Thanks,
