i think I'm going to get a 525. I'd also like to maybe get a 170 to use as a frag tank so they look nice next to each other. Do you guys think the sump for the 525 can handle both tanks? Whether it be for adequate filtration or the fact if the power goes out would the sump overflow? I love my reefer 450 hence wanting to get more but just don't like the way the plumbing, sump and brace in the stand are. I'd prefer to run my own 48" timeline sump or something like that
