the right side is where my skimmer, heaters, and probes are, or if i want to run carbon i have a sopt for that too. my overflow i use is the cpr 1200gph with 2-1" bulkheads. my return is 1.5 " with a custom return in my tank that directs water in all different directions with no dead spots but eventually i will add a closed loop to increase waterflow
but since i'm not using my canister filter no more my tank is not as clear, it was always crystal clear with my canister running, so i think i need to add filter pads between bubble traps which should solve that problem, i hope
