Just wondering what it is that is appearing on my crypts?

Algae, green spot and looks like diatom

Flourish Excel will clear this up if you use it as directed.

Nerite snails do a number on diatom algae, but excel works well, too.

Nerite snails only do so much, so fast and can be hard to get. Excel also makes your plants grow better - but it's expensive. I've always bemoaned the lack of an open source second source. Vinegar and ingredient X or something...
