Hello all.......I'm a long-time lurker, first time poster looking for suggestions. I have a 65 gal. tank ( 36" long x 18" deep x 24" high) stocked with tetras, otos, and a peckoltia. I have a Rena Filstar 2, and am going to add a second one. My question is - how would you place the intake and return on these filters? Currently, the intake is on the rear of the tank in the middle of the wall and the return spray bar goes from the middle to the corner. Would you put the new filter's intake in the middle as well and run the spraybar to the other back corner? Or put the intakes in the corners with the spraybars across the whole back? Or something completely different? Thanks for your help!
