Wondering what everyone is using in sump for media?
Drain on Each side, return pump is in the middle
Each drain goes into filter sock
Below filter sock is egg crate, heater is under it, on top of the egg crate is Poly-Fiber
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.
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?
