I was wondering whether PVC cement is reef safe? I know it is ok for drinking water so what about reef tanks? I am using it for the plumbing for my sump, so I hope it is OK.
I used it on my 125 for my external pump (twice) and I have had no problems. I let it sit for like 15 mins but I guess if you can let it sit a whole day that would be the safer bet.
