Clean glass should be top priority in an aquascape, or rather, in all beautiful aquaria. A murky sight of the underwater scape and its inhabitants due to an algae layer on the glass lowers the spectators' joy considerably.
Glass cleaners should possess various qualities. On the one hand, they must not leave scratches in the glass, especially in low-iron-glass tanks. However, on the other hand, they need to remove any and all dirt and plaques, and moreover, they need to be comfortable to work with.Blade cleaners come in different lengths so you can reach the entire glass walls of your tank, be it large or small. Blade cleaners like the Pro-Razor by Aqua Design Amano (ADA) enable you to remove plaques and dirt even from the most difficult-to-reach parts of the glass.
With cleaning sponges especially made for aquaria you can remove plaques entirely, too. Please make absolutely sure that no sand particles come between the sponge and the glass, as they would leave bad scratches.
