Was this the Rid-x that helped?
The thing about Rid-X and many other products like it, is they do not actually kill cyanobacteria outright, they are not a drug or a toxin.
The bacteria they add to the tank are aerobic forms that are beneficial for the tanks filter system as a whole, and simply out compete the negative forms for nutrients.
It is thought that these positive forms, also compete with pathogens that can cause diseases in fish, and help reduce sludge in filters.
Its kind of like eating yogurt (acidophilus type foods) that maintain a healthy digestive tract in humans.
When I worked in the water industry, we considered cyanobacteria nuisance algae, but beyond that my first hand knowledge is pretty pedestrian.
But the study below has some insights, especially looking at the cyanotoxins.

Here is a before & now picture from my 29g. There is a noticeable difference but not gone by any means.

Wow what a difference. I may start using Rid X myself.
Hmmm, Every summer around here we have constant warnings about toxic cyanobacteria outbreaks in the river. Stay out of the river, etc kills a few dogs every year.Hmmm... My gt Oliver has been almost back to his normal active behavior since adding the rid x and cleaning the back wall. Do you think it’s just a coincidence or from these changes?
Since it only seems to have advantages to having it added to the system I think I’ll just keep up on it. I’ve already added it to all my filters.
