Exclamation Brown algae on anubias

I have a 10 gallon low low light low tech with 11 neon tetras and 2 anubias. One of the anubias has a light dusting of brown algae at the tip of the leaves. Should I soak it in a bleach-water solution or scrape it off? I also have some brown algae on the glass and in the filter. Nitrates are a constant 5 and I am not dosing any ferts.

Sounds like diatoms to me, no need for bleach. Just wipe it with your fingers, for the plant that is. For the glass just use a sponge (One you didn't use for soap)

Bleaching is an option but only if you do it right. It will kill all the algae and make your plants looks nice. 20 cups of water to 1 cup of bleach. Soak the plants for 2 minutes then rinse them under the tap really well. Then put them in a bucket of water with a lot of dechlorinator. I mean a lot of it let them soak for a half an hour and rise them under the tap one more time to be sure.

Anubias grow so slow they're prone to algae. Bleach dip in a good way to clean them up. But you want to prevent algae to begin with. Anubias need very little light. I've had them survive for months in a baggie of water sitting on my desk with nothing but ambient light from the room.

If you want to prevent algae on your abubias add a floating plant like frogbit or duckweed. Or you can lower your photo period to 5 hours a day. Up it to six hours if you think the plants need it. The more anubias you add the better. More plant mass will help fight algae.

If your using led lights the light might be too bright. You can grow nice anubias in a 10 gallon with a single florescent tube. With a flourecnet tube the light is more evenly distributed. LED diodes are really focused and can cause problems in a low tech if too bright.
