Base rock

[new but handy]

J&L used to have a few boxes of it it was to the left of the door just bye the glass case for the expensive stuff! It was $50 for 50 pounds so it is much cheaper than live rock but it is very dense so it doesn't do the same job. it is good for aquascaping though. I put 50#s in my tank.
If you pay $5-6 for base rock how much is your live rock. ours isn't even that much
