I thought the point of bio balls was to collect bacteria used to filter the water. Wouldn't cleaning them remove the helpful bacteria?
Just wondering. I'm about the setup my first wet dry filter/sump and have never used them before.
The packing peanuts idea sounds interesting. Just make sure you get the styrofoam ones. Alot of them now are made of puffed up corn starch. They are supposed to be better for the environment but would melt in water!
Hi Spider!
Why not start out with a refugium in your sump? I wish I had... Now, I'm wondering when I'll get the time to change over from bio balls and what a waste of money... stress on the fish... taking the chance of cycling again...

I replaced my bio-balls with small pieces of really porpious live rock, then below that put a 3-4" sand bed, drilled holes in the divider so water could flow through without having to go all the way to the bottom slowing down the rate that goes by the sand.

FoxFace,
I do the same thing... Have you thought about using a bio-bag to pre-filter as well? I mean beyond the spong in the overflow maybe a biobag would catch more stuff, and it's an inexpensive add to the filter.

I just figuered between the sponge in the filter and the pad in the wet/dry everything would be o.k. I have been running it this way for a year and a half and have had no diseases or fish lost due to my water. Only fish loss was to bullies.
