Yes you are right. Unfortunately I have bought three different wave makers already and they all just seem to be too strong. Even when I've angled them upward it's still too much (also nothing allowed me to go under 50% power constantly). I've definitely lost sleep about this already. I also used random flow generators previously but they weren't giving enough power to really cause the random flow I was needing and it was like a weak hose with slight variation. I just went back to the flare nozzles that came with my innovative marine 20 gallon since there wasn't room enough to fit two pumps in the back for each rfg nozzle. Any ideas on a dc controllable wave makers that can operate at 10-40 percent so that is isn't too strong for a smaller tank would be appreciated. Thank you!That looks a ton better. Btw, flow is really important, I think you should adjust so that you can run your wave maker all of the time. Just adjust the intensity and you should be fine.
