SLSON Double Sided Sponge Algae Brush

The SLSON Aquarium Algae Scraper is a blue double sided sponge brush on a plastic handle, about 15.4 inches long overall. It is built for wiping algae and film off glass aquarium walls, and SLSON also suggests it for kitchen use.

Built for glass

SLSON states clearly that the brush suits glass fish tanks and is not suitable for acrylic or plastic tanks. A sponge can pick up grains of sand, and grit dragged across acrylic leaves scratches. If you keep an acrylic tank, choose a soft pad rated for it, such as the Aqueon magnetic algae scraper.

Handle and storage

The handle is premium plastic with a non-slip surface, so it stays in hand when wet. A hole at the end lets you hang it up so the sponge head dries out between uses, which helps it last.

Keeping the pad clean

SLSON recommends rinsing the brush pad with tap water before and after each use and storing it clean and dry. Never use soap on the pad, since residue can harm fish. A quick rinse is enough.

Routine use

• Wipe the front glass every few days to stop film from building up.
• Work top to bottom and stop above the gravel.
• Siphon the loosened algae during your next water change.

What it handles

Soft green film, brown diatoms and the light haze that builds between water changes come off with a few passes. Tough green spot algae usually needs a blade, so keep a stainless scraper like the KIRECOO algae scraper for those patches.

Who it suits

A light, low-cost tool for owners of glass tanks who want a quick daily wipe. The extra length over shorter brushes helps on taller tanks.

Replace the brush once the sponge begins to tear or stays dirty after rinsing. A worn sponge tends to smear algae rather than lift it, and loose bits can end up in the filter intake.
