DIY Algae scraper in 30 seconds.
I needed an algae scraper quick for my 20 gallon so I came up with this.
1x box cutter replacement blade or razor blad or really any one edged, disposable blade.
1x pair of chopsticks, the kind you get at the take out that you snap open.
Take your chopsticks and use your razorblade to cut a groove on the fat end of the chopsticks, the side where they join. Then insert the razor blade. You now have a small algae scraper for less than a dollar and a minute of your time.
