crypt spots
I just noticed all my crypts are getting small perfectly round spots on some leaves 1/8 to 1/4 " in diameter and smaller. What in the heck is this? thanks

Re: crypt spots
Do you have a picture of the spots? It could be green spot algae, which does make small round spots on the glass, the hardscape and the leaves. What color are your spots?

Re: crypt spots
I would say those spots are weird, but I'll bet anything several people here know exactly what they are. They just haven't spoken up yet.

Re: crypt spots
I am removing all infected leaves as much as possible. I am doing more water changes. I have never had this before and it nails all the Crypts in tank. The weird thing is the spots are perfectly round....just enlarge with time and seem to be dug in to infected/affected leaf cells. :confused:

OK it is green spot algae. It is growing on all plants. time for war!

Re: crypt spots
Oh, the round shapes are probably algae. Lower your light intensity will help with gsa.

Re: crypt spots
More phosphates also discourage green spot algae. Since I have been dosing double the recommended ppm of phosphates, about 10 years now, I have not had any of it in my various aquascapes. That may be a coincidence, but I doubt it.
