Hey all- first time posting, but not a noob, yet not a master either. Been reefing 5 years.
I’ve read forums saying waterweld is safe, and also so is the original Jb weld(the kind with the two tubes you mix together)
However, what about these? I usually use seachem coralcrete, but everyone near me is out. And I have corals arriving tomorrow.
Does anyone have any knowledge on whether these Jb products are ok? I like them over waterweld bc they are gray.
Thanks all!
