And .. sorry to be the bearer of bad news but you DON'T want the upgraded maxijets on a wavemaker. The powerheads have a slight shudder when they start up. This vibration passes onto the little swing arm which eventually distresses and breaks at the ball joint. You can't get replacement swing arms so you have to buy a whole new upgrade kit. I've had the swing arm break in as little as 7 or 8 weeks on a wavemaker, and last as long as 18 months (and counting) when on 24/7. The wave action is awesome but the little holder thingies just can't handle the constant start/stop action.

Thanks for the info Tony.
The PH's work fine without the upgrade kit or when mounted on the overflow. Since I started this thread I've found that they don't slide if I adjust the tilt to the PH; they do however, still sometimes tip. As for the wavemaker I know that PH's don't last very long with the starting and stopping so I talked to a well-known sponsor as to which PH he recommended for this application. He recommended the Maxi-Jets, so I ordered them. In hind site though, he may not have realized I ordered the upgrade kit as well. That's what probably does in the swing arm. What do you think?
