Hello,
I am working to get my new tank setup. A 170 Gal Fresh Coldwater tank. I am planning to use it as a simple planted and goldfish tank.
Anyway my question is about filtration. I am looking heavily into doing a sump setup on the tank. But from everything I see it appears that all I need in my sump is a couple layers of foam for mechanical filtration and then a bunch of K1 or other similar bio media. Why do canister filters have so many layers in them? Am I going to get enough filtration with nothing but foam and K1 assuming the proportions are enough.
