Cascade Canister Filter Producing Heat

[mr_tee0419]

Hey guys, I can't get my new 120 below 80. I attribute this problem to the 2 Cascade 1500 Canister filters I have running... has anyone else had a problem with these filters heating up the water like that? Also is 80-83 degrees going to be harmful for a FO tank?

82 to 83 F is ok for the fish. Just try to keep it consistant.
Does the tank gave a glass top? If so replace it with some egg crate and maybe add a fan

You neglect to mention the ambient temp of the room.

if the room is 85 degrees, the tank is going to be 85 or so degrees, give or take a few
