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

I got these in addition to my 1mp40 set at 60% in reef crest mode (yellow). A few things: Pros: 1. These things move water! Enough to shake all my sand in a 105g aquarium. I bought to increase the flow of SPS corals and the 2 I got are more than enough.2. Mods work fine. Wave mode (2) is really good. Can control pulse and wave strength. Set mine up so it doesn't slosh across the surface but still has good back and forth movement. Cons: Modes 3 and 4 do not use cruise control. So if you need variable flow, its max-min and every stage in between with no speed adjustment to set max speed. In my aquarium it was just a crazy current and messed everything up. Overall exactly what I wanted for the price. I looked at other Ecotech and the like but just couldn't justify $300+. These do their job perfectly. Let's see how long they last. ;). 4 stars because I want to set an upper performance limit in mode 4.
