Review on 🐠 Uniclife 3400 GPH Controllable Wavemaker: Enhance Marine and Freshwater Aquarium Circulation with W-40 Controller and Magnet Mount by Jim Larson

***UPDATE*** - After 72 hours I have decided to return the W-40 to the W-25. Anything less than a constant 30% is way too much for my 70 gallon tank, but I want to rotate. After 36 hours so far so good but still tracking. W-40 set to minimum setting, 30% sine, revs too much for my 70 gallon (52 x 31 x 13) tank. Recommend W-25 for anything under 100 gallons. I bought a pump motor power that will never be used. Too bad there was no time setting for "feeding mode" as I use automatic feeding 2 times a day which is set to a specific time as I sometimes work after hours or travel. Can buy a light timer that just kills its power combined with feeding time.
