Hey guys been in the hobby for like 10 years now just started up a new tank dry so I thought I’d go to percolate and get a bottle of IO bio spira which I’ve had no experience with using before usually use live rock this is my first dry rock setup, but it seems live rock is hard to get now I guess so I got real rock, anyways I added the bottle to my tank I’m starting and it looks like a bottle of detritus!! So I’m thinking it was used and returned anyone have this experience lmk thanks I just started this tank and now since I don’t know what it is I may have to start all over!!
