As stated in the title, have you used polygem? If so how was your experience and what was in your tank (corals, fish only, etc)?
I bought some about 7 years ago because I saw it on tanked, but never used it. From what I can find its still made and being used in public aquariums, so I'd like to think its reef safe.
