JBL Floaty II - L

JBL Floaty II is a magnetic glass cleaner whose inner half floats. That one difference matters more than it sounds: if the magnets part company, the inner piece comes up to the surface instead of burying itself in the gravel. JBL also bevels the cleaning edge to keep trapped grit away from the glass.

Key Features

• The inner half floats: no fishing about in the substrate when it comes off the pane.
• Bevelled cleaning edge: JBL's edge protection, designed to keep grit from being dragged across the glass.
• Protruding edge for awkward spots: reaches into corners and behind equipment where a flat pad cannot.
• Hands stay dry: the outer magnet does the driving from outside the tank.
• Two sizes, M and L: check which suits your pane thickness before ordering.
• Glass tanks only: an abrasive pad is not for acrylic.

Using A Magnet Cleaner Without Scratching The Glass

• Start the inner half near the top and work in overlapping circles downwards, so what you lift does not settle on ground you have already done.
• Stay clear of the substrate. The moment a grain of sand gets under the pad you are grinding it across the glass.
• Lift the inner half off the glass and rinse it if you feel any grit, rather than pushing on.
• Go gently in the corners. The silicone seams are the one part of a tank you cannot repair from the outside.
• Do the glass a day or two before a water change, then siphon the debris out.

Good To Know

• Glass only, never acrylic. A blade, steel wool or a metal-threaded pad will cut straight into an acrylic pane, and the scratches do not polish out in a filled tank.
• The usual way people scratch aquarium glass is to trap a grain of sand under the pad or the blade. Check the face of the tool before each pass and stay a finger's width above the substrate line.
• Strong magnets snap together hard enough to pinch a finger badly and can chip each other. Separate them by sliding rather than pulling, and store them apart.
• Keep magnets away from phones, cards, watches and anything else with a strip or a screen.
• Rinse the tool in plain water after use and let it dry. Never clean anything that goes into a tank with detergent.
• Scraping is the symptom. Algae on the glass means light, nutrients or both are in surplus, so look at the photoperiod, the feeding and the nitrate and phosphate readings as well.
• Pane thickness decides which size holds properly. Ask us to check the box against your tank if you are not sure which one you need.
