Hi, I'am starting a refugium in my sump this week and was wondering what my media choices are? Can I use live sand if so how thick ? I really do not want to use mud cause my system is already established and I'm afraid it will muddy my water.

I tried the mud for a while, didn't like it. Many people swear by it.
Alot of people have a sand bed with anywhere from 1/2" to a couple inches, and live rock in the sump, but I just have a small amount of rubble and the chaeto.
I don't like the whole sand and rock because it does trap detritus.

By rubble do you mean live rock ?

Yeah, but just small pieces. I put that in there to create a small rock pile to give copepods and amphipods a place to live and breed.
They are good food for many small fish.

how do you feed them to the fish? Catch them or they just get sucked into the tank via the pump?

They do travel up to the tank via the return pumps.
I've talked to a person who does pod research and she assured me they can make the trip without being sliced and diced.

Do they travel thru a pre filter 1st or when I build my sump I shouldn't have a filter between the refugium and the uptake pump ?

I do use some sponge as a kind of prefilter, but its just to keep the small pieces of chaeto from going through to the tank.
About every couple weeks I remove the sponge, clean it and let everything free flow for a while.

If you go for sand in the refugium, try to have 3" or deeper. The full benefits of sandbeds require that depth or more, and the larger the surface area the better.

I like 3" to 4" sand bed...
