Weird Fingerprint like substance forming on inside of glass?
I have this strange fingerprint looking stuff, at first I thought it was snail eggs but they have been there for a month and they are spreading, my flipper does not take them off with the fuzzy side nor the scraper side

Thats where the mouth of your snails have run over spots of algae. The radula doesn't scrape the glass clean so it leaves a pattern.

Mineral stains perhaps? The way I understand it is that these become etched into the glass and will have to be buffed out for clarity.
