Hey there! If you've noticed a green dust coating the glass of your aquarium, you're dealing with Green Dust Algae (GDA). Don't worry, this type of algae usually only grows on glass and isn't harmful to your plants. It's also common in new tank set ups, but usually doesn't stick around for long.
So, what's causing your GDA problem? It's typically caused by low nutrients and low CO2 levels in your tank. Direct sunlight can also be a factor. To get rid of GDA, the most effective method is to use a glass scraper to remove it on a daily basis. Make sure you're adding your fertilizers as recommended, as this can help to prevent GDA from returning.
If you're dealing with a new tank set up, it might be a good idea to keep an eye on your nutrient and CO2 levels and make sure they're within the proper range. It might take a little bit of trial and error to find the right balance, but it's worth it for a healthy and algae-free tank.
In the end, the key to dealing with GDA is consistent maintenance and attention to your tank's nutrient levels. With a little bit of patience and effort, you can keep your tank looking clean and clear.
