Warning about BRS rock.
Warning about BRS rock.
From the BRS website.
Eco RoX are free of nuisance algae and pests that are the most common causes for complete tank tear downs. Our rock is guaranteed to be free of apitasia, bubble algae, parasitic isopods, mantis shrimp, acro eating flat worms, little red bugs, fire worms, predatory nudibranchs, pyramidellid snails and other common pests
All of it is true but the part I put in bold for one of my rocks.
I placed the rocks I got from BRS, plus about 60 lbs of rock from my display, in a tub on the 27th of April after giving them a good swishing and dunking.
Last Sunday I went to do some more swishing and a complete tub water change.
The water had a brownish hue to it which I found odd.
The water didn't smell strong, I attributed the waters color to a few dead leaves that had managed to get in the tub...3 leaves to be exact.
Today, I went and pulled all the rock out, dunked, swished, complete tub change etc.
I noticed something very weird on one of my Eco Rox.
It has live macro algaes growning out of it.
I picked up the rock and gave it a good sniff, suspicion confirmed, it smelled like the bay at low tide but a lot stronger.
It smells baaaad!
You know the smell, the smell you get when you open up a box of "live rock"

that was ground shipped to you after it had already been out of the water for days and days...think Walt Smith rock.
The funny thing is that it didn't smell, at least not that I noticed but I didn't stick my nose to it, when I took them out of the boxes they were shipped in.
I was under the impression that this rock was dead base rock.
It is not.
At least not one of the rocks I received, IMHO, this is live rock left out to dry-ish, and not too long ago.
The other 2 appear to be completely dead.
Don't get me wrong, I am not slamming BRS at all, these rocks are freakin' sweet in their size, shape, and price but a rock this size (it is the largest of the 3 I received) placed in anything but a LARGE tank could very well cause a cycle.
I am glad I cook ALL rock before it goes in my tank.
I wanted to share so that other would double check before possibly harming their systems.
