bio- bale

bought a cy192 from cpr wondering what i could use in place of bio-bale to avoid eventual build-up of nitrates

LR rubble. Definetly get rid of any "bio" products ie: Bio-bale, Bio-balls, etc. If you rely mainly on LR for filtration you must make sure the water has plenty of contact time so a slower flow is a must!

And you may have to modify it a bit to keep the LR submerge. I used to have a CY192, when I removed the bio-ball and replaced it with LR, I put in a piece in the last chamber ( return part). This raised the water level and the middle chamber so that my live rock stayed submerged.

I'm just curious as to why a submerged bio ball would behave any differently than LR. It's just a substrate that will eventually be colonized by bacteria. Now is there a difference when a bio ball is used in a wet dry system that affects the processing of accumulated detritus? Also if you have a refugium growing macro and/or a DSB, won't it aborb these waste products?

The difference in a bio-ball and LR. Bio-balls hold on to the bacteria. That's it. LR absorbs the bacteria and will eventually eliminate it. A refugium is always a great addition to any tank. The macro, Chaetomorpha and Caulerpa being the most popular, thrive on nitrates and also will absorb a majority of it.

I have an old CPR wet/dry in my garage.

If you simply replace the biobale with LR, you're not accomplishing much more, unless you can keep the LR submerged - that will be the key.
