HELP! Chemipure replacing filter cartridge

Hi everyone

I am very new to this so please be patient with me. I have a 29 gallon oceanic biocube which has a little cartridge filter in the 3rd back chamber. I took it out and have a bag of chemipure. I need to know where the best place to put it in this tank configuration. The compartment where my bioballs WERE is empty now as I use my live rock for that with great success. I have lots of soft coral and frogspawn and trumpet coral along with 2 clown fish, a pajama cardinal and a small hippa tang. All are going great and my water parameters have always been good other than nitrate sometimes at 5-10. Any suggestions???? I left this in another forum as I wasn't sure where to post it.

 

I had a bio cube 29, in the compartment u have all the live rock at i had a polyfilter cut to lay across the bottom and thru a bag of chemi pure on top of it. I just counted on the live rock in the tank for filtration....

 

Thanks a bunch. You are the ONLY one who replied to my posting. I just checked all of my chemical parameters and everything was good....EVEN my nitrates were 0! My carbonate hardness is running a bit low at 7 (125) but all else is good. I am hoping that the chemipure is the reason for all of this. Thanks for your input.
