Rock is a combination of Limestone chunks, Reef Rock, and the Fabricated stuff you see around now these days.
All of the rock has been soaking in warmed, clean, saltwater with regular dosing. No Aptasia.
Free must take all. 150 lbs plus? 55g Tank 3/4 full of rock
PM me and I will send you a pic.
Deal is you pick it up in tubs, in my driveway. If you want the 55g glass tank you can have that too...
Thx
