I use a regular algae scraper which works great on brown algae, but does not work on green algae on the glass. The green algae is increasing day by day and I want to know the best way to get rid of it.
I use a magnet glass cleaner for the lighter algae and a plastic scraper made by kent for the harder green spots. You can also use a razor for really tough algae unless you have an acrylic tank. The short amount of time the razor is in the water will do no harm.
