I'm in the process of setting up 75 gal. and would like some input on filter and powerhead locations. I will be using a Magnum 350 and Fluval 304 canister filters, along with a 350GPH powerhead with pre-filter. I was thinking of placing Input/output of one canister on back left and one on the back right. I was going to place the powerhead in the middle. What do you think of this setup? All suggestions would be appreciated. Thanks for the help.
