BioMatrix rock

[laynframe]

I'm starting a new frag tank and I'm using this product as my primary bio filtration rock. I'm using crushed coral for a sand bed and running biopellets in a EliteAquatic reactor. Has anybody used this with good results? Just thought I would throw this out there and see what comes in.

If your buying a lot pond matrix is cheaper and doesn't clog as quickly.
