I do not have an exact solution for you as I don't know much about frogs. And without knowing your actual setup, I can only make some guesses.
Personally, when I start seeing algae, I always check the flow first and co2 second.
In your case, I would make sure that there is as little organics as possible (filter, clean tubes, decaying plants and driftwood, left over food, etc) AND that there is good water oxygenation.
The location of the algae is an important clue: is it directly in the flow, stagnant area, etc. The plants' health is another clue: why some of the plants are no longer doing well.
Meanwhile, trim off affected plants and vacuume the substrate + water changes.

Thank you for replying.
The frogs are poop machine and they like stagnant water, because of this I direct my spray bar toward the back of the glass to reduce circulation. I get the feeling that hadn't helped my cyanobacteria problem.
So far I've only noticed it in two places, growing on the roots of floating water sprite and I did notice some on my driftwood, that driftwood was immediately removed.
At one point my aquarium became quite lush, it was overgrown so I decided to trim it back a bunch. It never seemed to grow back very well unfortunately, my water sprite became quite brittle and brown and began to rot (though there was also new growth as well). I've read this happens to water sprite some times. I don't know what triggered it.
I've had my Eheim 2217 since last October and I've only cleaned the sponge once. I think it's overdue for a complete break down and clean which I am going to do this weekend.
I do vacuum the substrate weekly (it's sand) and I net any decaying organics I find (mostly brown broken leaves of water sprite..) and I've got my spray bar circulating the tank now. When I see affected water sprite I remove it, again it's not a lot of cyanobacteria but I am seeing it now and then on the roots, it hasn't taken over or anything thankfully but I am worrying.
I am going to do 25% water changes twice a week and break down and clean my Eheim 2217 this weekend.
If there is anything else I can do past that to get things back to normal I'd love to know. I do miss having a lush planted aquarium, it seems to have seen better days. Would giving the plants/driftwood a H2O2 dip help as well?
