Hello all I have been running a wet/dry on my fish only tank and recently purchased a used 180 gallon which I would like to set up as a Reef tank. It came with a CPR CY294 wet/dry and I have read so many things here about how I should set it up. Seems that people feel that with the Reef tank bio balls are no good. There seems to be a lot of conflict on whether or not you can replace bio balls with live rock. Talk of converting the drip tray to accommidate filter socks etc..... so basically I am completely confused.
As of now i am thinking of maybe using the filter sock material to be placed on top of the drip tray filter. Now the question will be do I replace the bio balls with live rock or chaeto?

), as the rock provides all necessary biological filtration. Trickle filter do a superb job of converting wastes through to nitrate; live rock does that, but also functions as a dinitrater. I did something similar to you, years ago, converting a 180 from a FW plant tank into a reef; never could get my nitrates under control until I dumped all those blue Dupla bio balls.
