Is this Dry Rock ok for my tank?


New member
So i just passed by my LFS and they were selling this dry rock for less than a dollar a LB and i purchased a couple of bif pieces then broke them off to a couple of smaller rocks.

My brother also purchased to dry rock and now they're starting to get coraline growing on them but i know he got tonga shelf and i have no idea what kind they are so before i put them in my tank i want to make sure they're safe for saltwater.


Heres a closeup of a piece


Anyways i pressure washed them so they're nice and clean.

thanks in advanced.!!

I used a pressure washer and some "high quality H2ohh"
no chemicals

the rocks have this yellowish tint that wont come off.

i cant wait to aquascape tomorrow.

Verify they didn't come out of a fish only tank that was dosed with copper before you start reefing on them... that seems pretty cheap.
