Many household cleaners contain ammonia and other harsh chemicals which can be toxic to fish and invertebrates. Fritz Glass Cleaner is ammonia-free and is completely safe to use on the exterior glass or acrylic of any aquarium. It removes dust, hard water stains and fingerprints with ease and makes a smoother surface for using magnetic algae scrapers. Also great for wiping down electronics and LCD screens.
Do not spray directly into tank water
For best results, spray onto external aquarium glass/acrylic and wipe clean with a soft microfiber cloth.
