Brown algae?!

[Fishmomva]

Hi - I’m having trouble with brown algae! I upgraded my tank about 3 weeks ago, keeping old filter media and a little gravel from my previously cycled tank. I’ve been testing my water regularly and it’s perfect. We keep the light on for about 12 hours a day. I have shrimp, Corys and Rasboras. What can I do to stop this stuff?!

Thanks!

Your lights are on too long and are probably too bright. Get a LED dimmer, and have them on for about 9 or 10 hours tops. It can be hard to find the right balance. If the shrimp aren't eating it it's probably cyanobacteria.

Try the common pond snail. They eat it up like a rat eating cheese.

I just got a new nerite that cleaned every leaf within a week of brown algae, I have another nerite that only eats algae off glass so a couple of them make a nice tank addition, they also don’t breed which is handy
