The QO 4000 & Mag 9.5 are both submersible pumps, not external

do not go for a quit one i have replaced 3 of them in the past and on 5000 they crack!! the way i used to realized is by getting a bit of eletric shock the first time i relized was because the corals in my tank looked pale and coldn't understand why !! then i saw a little salt deposit inside my stand !! i have gotten replced as it was under warranty but the same happened to the other 2 that the comapny replaced for me !! so now i have mag 12 that i use for almost 3 years and never a problem!!
