Setting up my 72 gal and still need heaters. Wanting to stay in the $50-60 price range or less. I was thinking of doing 2x 200W for reliability but was also looking at inline heaters to look nicer in the tank. I have only ever used submersible so I know very little about them. I'm going to be running a fluval canister filter on the tank. Does anyone have suggestions or recommendations? I want something adjustable temp wise either way.
