About every three weeks or so I have to give the algae a good scrapedown with a credit card blank.  It involves getting essentially my whole arm into the tank with some complicated manoevering to get through the narrow access at the top of the aquarium.  It takes a pretty good hour to get things sorted out.  I’ve been wondering about whether it’s worth getting a magnetic algae scraper to clean the algae without having to get all wet doing it.  Lots of good choices there, with some people advocating for “the flipper“, while the platinum standard (even more expensive than gold) seems to be the ‘Mighty Magnets‘ range.  What puts me off is the fear that they will scratch up either the inside (or the outside!) of the tank, whereas I’m pretty sure the credit card blank is generally problem free.  The other upside to a magnetic system would be getting in behind plants and decorations.  I haven’t been brave enough to pull the trigger on getting one of these yet, but maybe someday…

Lots of great videos about magnetic algae scrapers, but always for glass… bad sign so much silence about acrylic?
