Review on Revolutionize Your Aquarium with the Jebao SLW 🐠 Series SINE Wave Flow Wave Maker Pump and Controller by Jen Johnson

If you don't know her, take a look. I have 6 spreads on 3 tanks. They are smooth and disappear on my rear window. The broad wide pattern won't blast coral like a laser. There can be no question of noise. I have one (of 6) that arrived faulty and will be initiating a return today. It's a broken center pin and it broke within seconds of turning it on. All in all, I'm not complaining about it because I know it's going to happen and Amazon will take care of me. Buy these pumps. Oh, that's a huge jump in flow from a model 10 to a model 20. 10 should work at high speed, and 20 is almost too much on the lowest setting for my 60g cube. But I prefer several small ones instead of 2 large ones.
