Caribsea lifeRock cause cyano outbreak?

Has anyone experienced this? I have added the caribsea liferock on 3 separate tanks and after a few days later all 3 tanks had cyano. They are all separate tanks so there was no cross contamination. My tanks had been cyano free since setup. Weird part is cyano only appears on the caribsea rock surfaces. Is caribsea a sponsor here on the forum? Seems like they spray something on the rocks that contributes to the cyano since those rocks after blowing them out of cyano their coraline coating or whatever they spray also disappeared. Now I am battling a huge cyano outbreak on one of my big tank.

Just beaten this with chemiclean but took 2 doses. Tried blackouts and hydrogen peroxide with no effect. Been 2 weeks clean free so far

I have tried so far 3 methods. Chemi clean, red cyano rx and dr. tim's cyano method. Nothing worked. Always the cyano starts from the caribsea rocks. It coats the whole rock and starts spreading after siphoning them out

Well this is terrifying. I just got 60 lbs of these things for my tank upgrade. Wondering if it’s worth putting them in the new tank now

Well mine could just be a bad production batch. Who knows. Maybe you can cure them first?

I put one in my current tank and don’t recall any issues. I did rinse the dust off with tap water then let it soak in RODI for a while before putting it in so maybe that helped? I’m planning to rinse and soak these the same way, hopefully that’s enough.

I used 140 pounds. No problems. Maybe it is a coincidence. I did have new Marco rock get covered with it. New bare rock goes through phases of overgrowing stuff for a long time.

It takes time. These pics span 2 years.
