Ecotech Marine MP10QD Quiet Drive Non-Wireless Version (NOT REEFLINK Compatible)

Used this on the opposite side of my 22gal long tank's filter outflow. Fresh water.It goes weak enough to not trash your plants which is great. I wish they made one that could go even lower of an output for fresh water planted tank. Say, 1/4 as low as the lowest setting current goes.Bought a jl10 too or whatever but that lowest setting is way too high.
