RSM - Remove or replace ceramic bio material?

[RSM2008]

Sooo much cleaner!
I removed the ceramic bio filter bag and the Chemi Pure (it was ready for replacement anyway). Water flow is great and there is way less debris acumulation in the chamber.
Now I am going to fashion an egg crate rack under the return pumps to hold my ChemiPure above the bottom.
So I have: fine filter (rinsed almost daily), 1/2 blk sponge, skimmer (mine removes tons of guck) and finally carbon on the way back to the tank.
I'll keep an eye on nitrates to make sure my LR is doing what the ceramic was. Have been 0 0 0 for ages.
