I have 2 mag pumps currently in use within my system and a third as part of my water making set up/utility pump for water changes. I am noticing that a few screws and part of the casing is showing rust on 2 out of 3 of them. How bad is this for my system since they are both submersed in my sump (one for my skimmer and one for my return)???? They have been running for less than 1.5yrs. So i feel as though this is TOTALLY UNACCEPTABLE. Is this to be expoected? is it common? or is it worth me going to the company to complain but again more importantly is this going to negatively affect my system in the near future?
Thanks
