BOWFRONT AQUARIUM MAGNET

[D0ubt]

Hi there,
I have a 36 gallon bowfront aquarium that accumulates a small amount of algae on the glass at the base near the line created by the substrate. I am finding that a traditional aquarium magnet is not able to remove this algae as the glass its self is far to curved. Does any body have any recommendations for cleaning magnets designed for curved front tanks, or possibly another recommendation for cleaning?
The tanks dimensions are as follows- 30.7 in L x 15.7 in W x 22.2 in H (77.9 x 39.8 x 56.3 cm)

This is a picture of what the tank looks like for reference.
Thank you for the help in advanced :)

When I had a 72 bow I always used a rectangle mag float. Square ones were an issue but the smaller rectangle ones worked if the long side was up/down
