Removing rims is a CHORE! But it's so worth it
I have the same filter! I love it!
I have a replacement rim, I need to run a top on this tank because of the species of rainbows I plan to keep (they are big time jumpers) The rim on the tank cracked so it needed replacement. I would LOVE to run this full rimless, but I do not think its an option. I had heard great things about the filter, I test ran it just to check it out, I cannot wait to get it on this tank!
