So this brown algae appeared on my tank two days ago, this has never happened and I’ve had my tank for almost a year. I do water changes weekly and once a month I deep clean all the gravel and decorations. Idk what triggered this and would love some advice on how to prevent it and stop it.

Looks like diatoms. Completely harmless, and usually a sign of excess silicates in the water. Algae eating fish and inverts love to eat this, but even then it usually goes away quickly once silicates are reduced.

Nerite snails, amano shrimps, and otocinclus are great at eating diatoms.
All algae eating fish/inverts will eat it readily!

How do you reduce Silicates? It’s a 5.2 Gallon Betta fish tank, it’s only 1 fish in the tank.

I don't think there's a for sure way to remove silicates in the water. If you're patient, you can wait until the diatoms dissipate. If not, then you can get some nerite snails.
