I have a MJ1200 with the EcoSystem Mod for it. Do not have a tank anywhere big enough for this thing. According to EcoSystems it makes the MJ1200 10x stronger without using anymore power. This thing is a beast. I put it in my 28 Gallon, only 20" wide and it made a sand storm. Moved it up higher and thought water was going to come out of the tank. I do not have the bracket they make for it. I just zip tied it to the normal MJ bracket. But I lost the bracket now. The link below is the mod for it.
