JBJ 45g Build Help

[Ej Chavex]

I currently have two Jeabo pp4 that I want to use for the time being. Does any one know if the dry side magnet is water proof? I'd like to place them on the back wall but that would mean the dry side magnet would be in the over flow compartment. Ty for any help in advance.
