Sand Crushed Coral

[Osama]

I bought this sand off FB as I needed to top off my fine sand with some larger particle sand. It looks good but the seller did not know if the sand was used in a medicated tank. I bought over 200lbs and I like it.
How can I check that it is OK to use in my 500g reef DT

Anyone has any idea?? Should I just dump it?

I'd dump it, sand is relatively cheap.

You might try a copper test kit. Can you find out if the sand came from a Reef Tank or a Fish Only tank? If it came from a fish only tank I would assume that medication has been used at some point. With reef tanks most are apt to use hospital tanks.

I agree with you NanaReefer but the seller is a University student doing this as a " favor-project" for the school. Not sure exactly of what he was doing and how the sand got to the school...

I would put it in a bucket & rinse thoroughly with a hose. Then I would put it in saltwater from a water change with charcoal filter. Only add a little at a time to tank. Many of the medications that are not reef safe will stain the sand.

Thanks Blue Lip appreciate all ideas proposed here

I've had a bad experience with some sand from CL, and it was not pretty...

Actually the crushed coral turned out to be OK. Used one of the three buckets I bought and have it in the DT for a couple of month with no issue and thanks
