Magnetic Glass Cleaner 12-14mm — Floating magnet algae cleaner for heavy 12 to 14 mm glass on large tanks
The biggest tanks have the thickest glass and the most of it to clean, often a metre and a half or more of front pane. Magnetic Glass Cleaner 12-14mm (SKU: SMAGC14) is the thick-glass size of this magnetic algae cleaner, made for aquarium glass 12 to 14 mm thick. A handled outer magnet works from outside the tank while the inner cleaning piece follows on the wet side, lifting algae film from the glass. According to the supplier it is anti-scratch and easy to use, and the inner part floats, so it rises to the surface rather than sinking among rock or decor if it is knocked off.
Glass of 12 to 14 mm is typically used on large and tall aquariums, such as 150 to 180 cm displays and deep custom tanks, so measure the exposed glass edge to confirm before buying. The magnets in a cleaner for glass this thick are strong enough to hold through the pane, which makes handling important: keep the two halves apart when they are off the glass, bring them together only with the pane between them, and store the cleaner away from phones and bank cards. On a large tank, divide each pane into sections and work them in turn, rinsing the inner piece as it loads up with algae. A magnet will not shift hardened spot algae or coralline; use a scraper for those and keep the magnet for the regular film.
Usage & Application
When to Use
- Large display tanks: Aquariums of 150 cm and more, built in 12 to 14 mm glass.
- Deep and tall tanks: Reaching the lower glass without arms in the water.
- Public and office displays: Routine cleaning of big viewing panes.
- Fast film growth: Brightly lit tanks that need a weekly pass.
Cleaning Technique Guide
- Confirm the glass: Check for 12 to 14 mm before first use.
- Join with care: Hold the inner piece against the glass and bring the handle to it slowly.
- Section the pane: Clean one area at a time with steady, overlapping strokes.
- Stop short of the substrate: Lift away before the bottom edge so sand is not dragged across.
