I've noticed some white spots on my glass and LR that are hard and have some raised white bumps on them. They are tough to remove. Can someone please id this for me? Are they calcium deposits and should I remove them?
It's been up for 9 months now. Unfortunately, my test kit doesn't test for calcium. I don't think they are pods because they aren't moving. ?? any idea? Thanks for your help!
If you look really close do they look like they have legs almost like a very very very small starfish? I have seen these appear in my tank recently
