Well, holy crap. I've asked that question about using seios with a wavemaker and kept getting a resounding NO, don't do it, standard wavemakers used for other powerheads, like the redsea wavemaker, would burn up the pumps. So how much is the seio controller going for? If it is affordable perhaps they will be giving Tunze a run for their money and perhaps entice them to lower their god awful prices!
