I might be getting a 400 gallon food grade plastic tank for free,so I thought to myself that it would make an incredible sump!
Now if I get that sump and fill it half way that would add 200 gallons to my system. I would not be putting much in the tank besides my return pump.
Would I need to upgrade my scrubber as the only thing changing is water volume ??? Nothing in the display tank would be changed.
