Fluval Spec - LED replacement

I bought a Fluval Ecobright LED as a replacement for the original Spec tank light which was over 4 years old. The new light is much brighter and now my Anubias have developed GSA where they are exposed to the light. Tried removing it w/a soft toothbrush which didn't work. I'd hate to lose these well established plants. I've stopped using the 100% setting and am using between 50-75% for around 8 hours. Will the GSA go away on it's own?

Anubias is tough stuff. Follow the directions for a hydrogen peroxide dip you can find on the forums and along with the decrease in lighting there's a good chance it will vanish.

Thank you Boris dude. That was an option I was considering, tried it recently on some Hydrocotyl that had cyanobacteria. I was hoping it would go away just by reducing the intensity of the lighting. Is it necessary to be manually removed first? Cannot believe how it doesn't budge by scrubbing with a toothbrush.

You're welcome. When it dies off it gets soft and pale. Shrimp and certain fish will eat it.

I have a couple of Nerites so hopefully they'll work in tandem w/the reduced lighting. I'll use the H202 as a last resort if I don't see any improvement on the Anubia's leaves. What type of shrimp eat it? I had a ghost shrimp up until recently, maybe I should replace him/her?

If you by chance use Seachem Excel you can pull the plant and "paint" it onto the leaves or dip it into a small dish with Excel. I tried that personally a while back for GSA on some of my anubias, just painted it on waited 3-4 minutes and put them all back in the tank, all traces of GSA were gone in a couple of days.

Did you rinse off the Excel before adding the plant back to the tank? I've been spot treating the plants with Excel leaving them in place. Might be seeing a slight improvement since doing so.

Nope I just let it sit for a few minutes out of the water and put the plants straight back into the tank. And it took a few days for me to really see that it was disappearing but it completely went away.
