Ok I got my 2 jebao OW-25 wavemakers plus controllers. Initial impression is that they are awesome! Time will tell if they stay great, but for now I couldn’t be happier. They were $60 a piece on Amazon. These little guys move a lot of water and are basically silent. The magnet holds them quite firm, no problems with mounting. The controller is rather basic but has a bunch of functions. Despite the different settings, only one or too seem useful, but that’s ok because I can get a really nice wave going. Realistically, I could have gone with the next size up but that one wouldn’t have shipped for a while so I went with these. Either way, 2 OW-25’s does a fine job of moving water in a 90 gallon 4 foot long tank. I actually was able to replace 4 old powerheads and have more flow with just these two! If I fine tune the pumps to create a perfectly timed wave I have too turn the pump power down to keep it from splashing over the top of the tank. I personally like a ton of flow, so rather than a perfect wave I tuned it for maximum flow with a more random wave to keep it from splashing over. You can tinker with the frequency of the pulses on the different settings until you get something you like. I really can’t imagine needing more than what these offer which is why I’m not sure I can justify a more expensive brand. The only thing I can’t comment on is how long these will last, which is the only reason I think you could justify a pricey brand name powerhead, and honestly, I’ve had expensive equipment die prematurely too. If you need a wavemaker and don’t want t spend a small fortune these are a good choice.
