The magnetic algae scraper is the sixth wonder of the world to saltwater tank hobbyists. it is easy to use, and it does magical things like removing the haze algae that grows on your tank’s glass, revealing the wonderful world inside. Better yet, you can use it without getting your hands wet!
The way the magnetic algae scraper works is straight forward. Two opposite pole magnets are enclosed in separate water proof casings. Then a soft material like felt is applied to the outside of the casing to help prevent scratches. One magnet goes on the inside of your tank, the other on the outside. When the two sides get close to one another, they couple and will hold each other in place.
The aquarium surface is then scraped clean by moving the magnet back and forth or in a circular motion.
More stubborn algae like coraline algae can be scraped off with algae scrapers that have a stiff blade although even these blades don’t alway get the job done.
Why would hobbyists hate such a wondrous cleaning invention? Because algae scrapers can accumulate hard substances like sand or calciferous worms. Once trapped in the algae scraper, these hard substances can scratch your tank’s viewing surfaces. This fact is especially true for sratch-prone acrylic tanks that scratch if you look at them wrong.
The simple solution is to scrape carefully and to store your algae scraper outside your tank like I do.Browse the Store! Questions?
