"Ultra clean! The ONLY rock I trust to put in ANY tank at ANY time and not worry about leeching, ammonia spikes or having to wait till it cures. Just a small rinse and ready to tank or aquascape!! I always see people saying Marco Rock has to be cured. I guess they mix up curing and cycling. I have NEVER needed to cure it. Everytime I get a box I feel like a big kid about to play with Lego toys." - Romeo J. M. 

"Just received my shipment a few days ago. Beyond happy with all the different shapes and sizes sent! First time reefer and didn't realize that I wouldn't have to cure this rock. Bonus for me
