So, I had a seam go in a 200G today. I'm not going to say what brand because they treated me great! The tank was two years out of warranty and within one hour of my first call they said they are sending me a free complete replacement setup. Tank, Stand, Sump the works! While I wait, I have tons of coral, fish, inverts, and lots of rock jammed into a 20g frag tank and a 10g frag tank, plus garbage cans, coral on top of coral on top of coral. I'm going to setup my current 40g sump as another tank tomorrow to make more space. My question is would you go with a HOB filter or a Canister to handle a heavy bio load temporally? Thanks for the input.
