Sorry. Worth noting that information on that page seems inacurate. It says in one part it is 12 volt and another says 24. I spoke with Jeff and it sounded like this would be more like version one in that it would have 12 volt but he was going to get back with me. I don't know anything about the hydros. I hope I haven't jacked your thread.This is the only thing I read that sucks: NOT compatible with HYDROS WaveEngine
Hope it ends up working out for you.
