Backyard Aquaponics
A place to discuss aquaponics

I used the marble cause I had a bag of it for landscaping. It was going to be used inside, and needed to look good. I'm probably going to use crushed granite in the GBs, we have a lot of that here in NC, and I think it would look nice as a landscaping rock.

In this case it was 91% due to convenience, 8% to help it look good for the wife, and 0.75% for buffering, and 0.25% to get people to ask questions. I guess I'm most successful on the least important of my goals! I hope this isn't a harbinger for my future in AP!

works for me
