Hey guys, I was looking at some photos of my Fluval tank where I have my Betta in and this Cyano was happening. The aquarium has an output flow over that comes out the top and trickles down. Back then (when I first got it) for some reason the height of the fountain was higher and now it isn't. I'm wondering if this could be the culprit and my water does not have enough movement as before. I cleaned the Cyano off the log and the Java Fern. I also vacuumed the gravel (as I normally do once a week) and did a more than partial water change to see if this helps. Tank looks good. Now to see about getting the flow back up to where it was. I don't know why it has slowed down. Nothing blocking anything that I can see. I'll keep you posted.
