Review on 🐠 Enhance Your Aquarium's Water Flow with Jebao FBA_SW-2 Wave Maker - Controller Included, 132-660 GPH by Dnasty Julius

Handy Form Factor purchased for use in Fluval Evo 13.5. It worked right out of the box, but the flow is still too strong to use at less than 20g. I've heard of others using it successfully, but I tried pointing it in any direction and it still moved the sand and blew my corals off on the lowest on/off settings. The Else mode, which is her advantage, was out of the question. The problem is that it works with a standard 12V adapter, so you can't halve the power like you can with the RW-4 series and up (which work with 24V power supplies). If you buy and Square Trade's guarantee is valid, buy this too. These pumps either last forever or fail within 6 months. An additional $12 guarantees you a 3-year lifespan, which is all you can ask for.
