Help with identifying this one

Hello everyone,

Thanks in advance for your help. I have been battling with this Algae for some time. Your help is appreciated. Tank is running for more than 18 months. I have been dosing NoPoX for few months.

Looks like diatoms and some green algae. Possibly some brown algae too. PO4 is at a good level, but reduce the nitrates to below 10 should help. Diatoms go away after 2-3 weeks. If the other stuff stays then look into some algae eaters.
