FL!PPER Pico Aquarium Glass Cleaner - Magnetic Fish Tank Cleaner, Scrubber & Scraper, Algae Remover, Aquarium Cleaning Tools

It works great! It slides around nicely, scares the fish but it’s cute when she flares at it anyhow.

Strong magnet, scrubber works good, scraper is so so but it works, overall it’s a nice small sized cleaner and I like that I can work it around some of my rock work in hard to get to places

This works good for scraping all kinds of algae off the glass. However, if you have any sand at all you run the risk of picking some of it up and scratching the glass if you use the Velcro side. No matter how careful you are there's a pretty good possibility it'll happen eventually. Some sand is magnetic and you must causiously avoid kicking it up and grabbing it while cleaning. However, if you are careful about it this is a quick and easy product to use! For what it cost, it will last years!

So I was very surprised when I received this product as this item is super tiny. I have it on an innovative marine 20 gallon long saltwater aquarium, but it works very very well at cleaning the glass and getting the algae off.

Not a bad little product. Would recommend for a small tanks.

Works really well. Magnet is super strong and does the job. impressive product

This little guy would be the perfect flipper for my nano tank, which is why I'm so disappointed that both the ones I've gotten - the second as a replacement for the first - have had the rim that basically gives you any sort of grip on the outside half of this scrubber had come broken off of both in a thin black plastic ring.I noticed, after realizing that BOTH the little scrubbers had this problem, that the plastic packaging they come in was work to the point that it had holes in it right over this rim, which is probably the most fragile part of the whole thing but has the misfortune also to be the most protuberant. I would guess that they were all processed through some sort of machinery that crushed them/wore through the plastic with friction trying to get things from point A to point B.Which STINKS. I've heard flipper praised all over the place, which is why I was willing to pay for it over a less-well-known brand, but this product, at least, suggests they don't live up to their own good press. This is a lot more low profile than even the next smallest option, which matters for my small tank and, frankly, my branding allergy. I'm really sad it didn't work out - but I also couldn't recommend this product to anyone else knowing that there's a high likelihood they've all been similarly broken/rendered defective.

Strong magnet, about 1.5 inch by 1.5 inch square. Eliminates most algae from glass, but don't expect it to scrape away coraline or other calcified algae.

It works but if you have sand,it will scratch your glass.
