Hello. I have these tiny white dots on my glass. I did some research but I am getting mixed answers so I wanted to be certain. A couple showed up a while ago and noticed them. More and more are coming even when I clean them off of the glass with my tank cleaner/ scrubber. They won't just scrub off you have to use the metal scraper side of the glass cleaner to get them off, so they are on there pretty good. Here are some pictures hope it helps and thank you for the confirmation.
