So I was cleaning my skimmer tonight and found that the back of the pump is now starting to rust up. It is a bubble blaster HY2000s and the skimmer is a super reef octopus xp-2000 cone skimmer. I think it might be a sign I need a new skimmer considering just the pump is $200-$300. My tank is a 180 reef tank with a sump and refugium for a total water volume around 230 gallons. I have a footprint in my sump of 14.5" x 14.5" with a height restriction of 26" for the new protein skimmer. Does anyone have a good suggestion on what to get? I know everyone prefers different brands but just thought I would see what might work for me. Thanks for all the help.
