I have a ton of these. I know when i did stir the sand around before I installed the canapy (harder to get to the bottom now) it would just mix/wipe away.nassarius snails
You right there are bubbles there, I have always stirred the sand up when the color and bubbles would show up. Now that I can't get to the bottom with out removing my hood it just has been getting real colorful there. Can you explain what is going on. Since LFS stores haven't been telling me and I would like to know for future reference.I'll bet money that either bubbles can be seen or will be seen in a few more days right along side the "coloration".
