I've recently ran into this problem after removing a canister filter and trying to find a wavemaker to replace the low flow it provided in my aquatop 24gal. I've tried multiple wavemakers recently with no luck. Now this probably has more to do with my tank already being established and not being able to move rocks and coral around to suit the water flow but my experience with what i recently tried:
Hygger easy control Dc Wave Maker 9w; it was quite and small but no way to angle it, moved a ton of water for a little pump at 660gph at lowest settings. Has wave, pulse and constant flow settings along with higher flow controls.
Sicce voyager nano1000: poor quality imo, rates at 270gph, some what small, great direction capabilities but the noise and vibration was the biggest downfall for me, could easily cause seal damage If the sound don't drive you crazy.
Nero 3: ugh this one hurt at around $200 be aware of the return policy from where you buy as i didn't realize
BRS has a no return on items that touch water and google told me it's programmable down to 20gph which was not true. It's lowest flow is 663gph, it has a directional pivot it sits on that gives you very little angle, that is if it stays in place as it has a tendency to want to correct itself on the magnet. But overall it's quite, programmable with app and pushes a wide flow only.
Overall they didn't work in my situation as i need something in the 200gph range that won't be noisy or vibrate my tank apart.
