Mag floats are great for touching up on algae. Typically they won't get that hard green spot algae, but they can take care of other types. These are for glass aquariums only. Only the large comes with the blade scraper included.

Our personal recommendations for sizing:

Small: up to 20 gallon aquariums - up to 3/16ths thick glass
Medium: Up to 55 Gallon aquariums - up to 3/8th thick glass
Large: Up to 180 Gallon Aquariums - up to 5/8th thick glass(comes with blade scraper)

Great Product

Well, I had the dreaded Hard Green Spot Algae on my 60-gallon freshwater planted tank. Nothing less than a razor blade to scrape the sides at water change time would cut through it. I saw the add from Aquarium Co-Op's email and frankly could not believe the reviews saying this would work on my problem. I ordered the large Mag-Float cleaner with the scraper and was blown away with how easy it worked. Took me about 5 minutes to do the front and one end. No more wet arm. This product really works. I think only the large size comes with the sharp metal scraper attachment. Try it, you'll like it.
