Wondering what everyone is using in sump for media?
Sump Setup
Drain on Each side, return pump is in the middle
Each drain goes into filter sock
Chamber 1
Below filter sock is egg crate, heater is under it, on top of the egg crate is Poly-Fiber
Chamber 2
Flow from chamber 1 is at the bottom
In this chamber I have poret foam, 20 ppi, does not fill the entire chamber, it only about 3 inches high, but goes the entire length.
Chamber 3
Flow from chamber 2 goes over the top
Eheim SUBSTRAT Pro Biological Filtration Media
I have about 10 boxes of fluval biomax, that I was thinking about adding to chamber 2, and doing away with the poret foam?
I also have 2 gal of Seachem Pond Matrix, it looks like rocks, I was thinking of adding as well.
Thoughts on this?
Also open to other ideas how to move media around?
