If I'm running DC pumps, heck yea, I'm gonna run dual pumps. That's why I run a 20+ year old Eheim pump. They're the working mules of our hobby. Also if power goes out, what then, single or dual, they both have same conclusion. BummerIt's been said that your return pump is the heart of your system. I believe and agree with that statement! My reef tank can survive quite a while without lights, dosing, skimmers, reactors, etc. but it won't stay alive long without the return pump providing flow and circulation of the water.
So why do most of us only have one? Maybe you have a back up, maybe you don't but today let's talk about actually having TWO return pumps running at one time.
Do you think it's a good idea to have a dual return pump set up for your reef tank? Why or why not?
