I'm not really sure. I bought it off some1 for $25 and it was about 80lbs. I took what i needed and sold the rest for $35 because there was still like 40lbs.
I just threw in a piece of LR for the 90g so it should be going thru a cycle now. Never had time to check the water parameter b/c the wife and i had a weekend getaway.
well, nothing to really report. i checked the para once and they were so colorful i 've left it alone. need to check again and see where the cycle is going. it shouls be done by now if now i'm sure i know why.
