My aquarium sand is constantly developing brown/green patches, which I am assuming to be algae. Please see a quick video below.
The glass sides of my aquarium also seem to develop dark spots (algae?) and I don't know what else to do other than scraping it off but it comes back in a few weeks

When I check the water parameters, I do see nitrates are too high. I am using this product during water changes - "Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier", but doesn't seem to be helping a lot.
Please let me know what other steps I can take? This is a 55 Gallon tank with just two fishes right now. I have taken out the air bubbler as I read that more oxygen is detrimental to the anaerobic bacteria that processes nitrates. I am wondering if I need to replace the whole substrate or even the filter media? I have never replaced the filter media nor the sand and the tank is about 6 years old. Please let me know your thoughts. Thank you!
