What's the best way to keep algae off my Anubias without harming the plant? I've got a 20-gallon tank with moderate lighting and CO2 injection, but the leaves keep getting covered.

I've had good luck with nerite snails. They're chill and won't mess with the plants. Also, try reducing your light period by an hour or two. Algae thrives when the lights are on too long.

My Anubias always gets algae too. I just wipe the leaves gently with a soft cloth during water changes. It's not perfect, but it helps.

Yep, nerites are the way to go. They're like little cleanup crews. Also, if you're dosing ferts, cut back a bit. Too much can feed the algae.

I'm new to this. How often should I wipe the leaves? I don't want to damage them.

Once a week during water changes is plenty. Just be gentle, and you won't hurt the plant.

I've found that floating plants like Frogbit can help by shading the Anubias a bit. Less light means less algae.

Thanks for the tips, everyone. I'll try reducing the light and adding some nerites.

No problem! Let us know how it goes. Also, keep an eye on your CO2 levels. Too much can sometimes cause algae blooms.

I've heard that adding a small powerhead can help by increasing flow around the plants. Has anyone tried that?
