So I am wanting a sump. I have a small tank to pretty much house my skimmer (hob) and a return pump. I need to life the water 3.5feet to make it back up to the tank. I want the water to flow slower in the sump so it gets a lot of filtration, I am thinking about planting mangroves and having a ton of macro algae in there. I know you want 5 or 6 times the volume of your DT but how do you do the life part again? (head?)
-thanks
