Ecotech MP40s

[Skidog]

Or anyone that has any doubts, the mp40s are amazing. I saved and.got two for my 90 gallon fowlr and soon to be reef. These things actually have cleaned my tank, sandbed and rock. They take awhile to figure out how to program the different settings but I'm amazed at how they are beneficial to the health and look of my tank just using them at the basic water movement setting. I had doubts but not any more.
