Review on Tunze Care Magnet Nano: The Ultimate Solution for Glass Aquariums Up-to 3/8 by Darcy Rud

I am glad I bought this item. It works exactly as advertised and as soon as you take it out of the box it's clear that it's well built. Once you have read and followed the instructions and are using the Tunze Care Nano it is also clear that it is well designed. It's almost perfect for my purposes - I recently bought a new flashlight which showed a lot of white algae build up on the pane of my aquarium. The first time I used it, it took me about 12 minutes to clean 3 sides of the aquarium. Tank. I started with the front, which is curved. No problem; I used an up and down motion and it happened instantly. The Care Nano definitely works with curved glass (woo!). Even corners are no problem; There is a video on YouTube showing the technique, but actually there is nothing to see. Just stop at a corner and move the handle in one smooth motion and the scraper side will follow. It's not hype - the magnet is REALLY strong. I also didn't find such a big disadvantage that it doesn't float. Once when I dropped it, I quickly retrieved it with a scraper and it reattached it to the handle. It also hangs unobtrusively in the tank. Place mine in the corner next to the filter as shown in the image.
