Man I hope I am not double posting. I had a post written and not sure what I did. Mods, I did please delete the other. I started curing these rocks back in July. About 4 months ago I read and also someone on here said I should apply light to help get bacteria growing. I do the shrimp thing, etc. It's been about 6 weeks since I checked on them. Today I noticed the rocks look like this. Covered in a green slime. The salinity was 1.038. I got it down to 1.025. I kee them at 80 degrees. I wanted to use some this weekend as I want to move my 6g into a 16g biocube. However, I don't think I can use them looking like this. Should I do a 30 day blackout?
