Fuge setup help

[Bigjohnwoody]

Ok I have a 120 rr with about a 30 gallon sump! It is a three chamber homemade sump so one section is going to be my fuge! Can I just leave it bare bottom and put extra live rock in there and then chaeto on top? The water is very slow moving through it! It almost looks stagnant but of course it's not! I am wondering on the cuc I should put in there if I leave it this way? Don't want to put sand in since it is only 13 inches high this will take up to much room and leave me with less room for live rock and chaeto! Also want to keep chocolate chip stars in it to feed to harliquin shrimp! Want to rotate the stars and cut off a leg at a time to feed to the harliquin! I have not bought anything for my tank yet as it is still cycling with just live rock this is all future planning. Thanks

The stars in a sump where your cutting off legs can foul the water in your DT. I would put the harliquins in a different system or keep the stars in a different system so you dont foul the water.

What if I was to cut and then say dip the stars in freshly made water and then back to the fuge. Would that help?
