Thoughts on using a canister filter and how i have it set up? I am using a canister filter since I don't have the funds or space for a sump but still wanted to increase my water volume. In the 1st chamber, I have my protein skimmer. In the 2nd chamber I have the intake for the canister filter and macro algae (I removed my media basket). In the 3rd chamber, I have the return for the canister filter. The filter has one filter pad, lava rock, carbon and purigen.
