Media In Filter Socks

Any thoughts on putting media in your filter socks?

I have never placed media in filters socks but have heard people do it.

90 pounds of rock in your display tank should be enough biological filtration. You can probably (slowly) remove the bio balls. If you're attached to your balls, then what you can do is throw them into a mesh or some other porous bag and just hang them in your display tank while you do the transfer. That should keep the bacteria on the balls alive while you do the transfer. Bio balls are really unnecessary if you are using cured porous rock (like the marco rock) in your display tank.

That might be difficult to do, I'm not very flexible...



The sump was initially sized and intended for a 90g fish-only freshwater tank. I decided to make do with it until I needed to change it up. I hesitated including the bio-balls initially but decided it may make denitrifying easier in the short term (start-up).

I think what I’ll do is just put them in a bucket of tank water, do a water change, install the new sump, and then put the balls into the refugium chamber for a while until I’m confident the tank won’t cycle.

i currently run my rox carbon in one of my mesh filter socks. i suspect it doesn't work nearly as well as running it fluidized in a reactor but i can't say for sure. i do love how easy it is to rinse and dispose of though!

the carbon eventually is all pushed against the bottom of the sock. i'm not sure how good flow is through all of it once this occurs...
