I started a 29 biocube when I moved into my new apartment about a week ago. I had a hermit crab, fire shrimp, and 2 nassi snails in a 6g so I put em in the 29. I put about 9 pounds of LR
in to get started with a bag of LS
(it's a 1.5in deep bed. I used live seawater to help the cycle along too (I'll mix my own once it's done cycling).
One thing I have noticed is some parts of the LR
are getting these black stripes, and I was just wondering what this could be. I got 5g of RO
water from the LFS
that I have been adding in for top off until I get my ATO setup again. I posted 2 pictures below, but they look worse then what it really is. Should I just let it rock for a bit or so I need to do something about this now?
