so am setting up my mp40 on my new 75 cube, but for some reason one of them wont stay put. i have it set to 3/8 but it keeps sliding down and falls off my tank. if i go to1/2 setting it blinks green and red, which i think it means the propeller is stoke or something. i think there is something wrong with my wet side but not really sure. i have the plastic in between the dry side and the glass. i get it a lil wet so that it might stick a lil better, but honestly doesnt really help. I know it works but wont stay put.
