I know there was a topic about 3M Colorquartz and people were saying it is not Ray safe for long term. Due to the bag saying it can cause humans cancer etc...
I know its used in pool filters and if no one has got cancer from swimming in those pools yet, I am sticking to the varient colors of 3M Colorquartz S Grade
No Rays but do have lots of Tankmates that use the Quartz. Plus the Ray threads are the only ones to get good info for Tank Bottoms. JMO
