Diatoms :(

Recently i have changed my lighting to a brighter led. I noticed brown spots on the glass and substrate and wiped it off and did a 25% water change. 2 days later, it worsened. I am adding plants to the tank tomorrow and i was wondering if adding plants would reduce the algae or would the brown spots grow on the plants? Also this tank has been set up for around a year and only recently started having brown spot algae
pH- 6-6.5
Ammonia- 0
nitrite- 0
nitrate-10
lighting-12w led
tank size-15gallon

plants im getting:
Pista stratiotes ◊ 1
Cryptocoryne wendtii green ◊ 2
Hygrophila Polysperma ◊ 2
Sagittaria Sabulata ◊ 3

Thank you

Diatoms usually appear in new tanks, and go away on their own as tank matures.
Could you have recently disturbed the substrate or removed/added new substrate?

Oh yes i did change the substrate from gravel to sand and dirt. But that was about a month ago and there was barely any algae till few days ago. However my tank has already been set up for 1 year+

Otocinclus love diatoms.
Silicates in the sand /possibly dirt as well, will feed the diatoms till the silicates are mostly consumed.
Twice weekly water changes can help a little, along with keeping filter material cleaned in old tank water you remove during the water change.
Diatoms are easy to wipe/rub off broad leaf plants with your finger.
Keep glass cleaned with clean paper towel folded into fourths.

Yeah just add Otocinclus. They will take care of the diatoms. I had an outbreak in 2 tanks a few months ago and a group of Otos in each tank took care of it in less than a week.
