Got these green hard algae on glass that are extremely hard to get it off. They are mostly at bottom of tank above the sand.
Previously using the long scraper and dip yr hand into the water to scrape them off. Very messy n feel like the natural oil on my arm dirty the water cos my skimmer foam always subsided when I stick my arm into the water.
Reefer Djvin recommended this algae scraper to me and So decided to give it a try.
I got 2 cleaner magnets, 1 is LV grade, 1 is pasar malam grade. Have seen this scraper long ago but couldn't bare to super glue the scraper to the better grade magnet. Reefer Djvin has his scraper glued to a cheap magnet n it works.
So I decided to try out.
After waiting for the glue to cure, I tried it out this morning. It is like running just 10m of the 2.4km throughout. Effortless!
Point to note is u should select a magnet that can be moved around easily. As if the magnet is too strong, there might be harder to xontrol it around.
