Nope fluorite. It's evidently nasty stuff- I will have to rinse way better next time. I do want sand but how would I go about putting in sand after this stuff is already there?
You could drain the tank, add the sand and then carefully add water by pouring it slowly onto a bowl or plate. I think your fish would need to stay in the 2.5g for a while longer though.
