FLIPPER Max Magnetic Aquarium Glass Cleaner – 2-in-1 Scrubber and Scraper, Hands-Free Fish Tank Cleaner for Algae Removal, Safe for Glass and Acrylic Tanks up to 3/4" (19mm), Freshwater & Saltwater

I have a 112 gallon aquarium that's in the wall of my office. When I would clean the front I would use a magnetic cleaner or I have a blade on a long handle, but the problem is getting the tough algae and knowing where it is. The normal mag scraper does an okay job but at some point the tougher algae shows up and it take a lot of going back and forth between rooms. I just tried this Flipper Magnetic Aquarium Glass Cleaner and WOW it worked perfectly! I could use the blade on my glass aquarium and easily and quickly remove the stuff on the sides and near the sand. This is a game changer for me. HIGHLY recommend. Plus the surface area of the non blade side is larger than the other scrapers I've used, and the magnet seems stronger, which is a big deal for me because the glass on my aquarium (from glass cages) is pretty thick.

For years, I’ve used other scrapers (magnetic, AND “scraper on a stick”), and this one beats anything we’ve tried so far. I have to say I was skeptical before clicking “buy now”. We’ve got a 50 gallon tank, and this standard sized scraper cleaned the glass in minutes. The only thing I wish is that I had one of these from the start. It functions exactly like the description says. The materials are very high quality, and the magnetic strength is exactly enough. 5 out of 5 stars, would do this again. Will gift this to friends and family who also have aquariums.

When looking at this and deciding to buy it, the price seemed rather expensive for what it is... basically a few magnets encased in plastic. And upon receiving it and opening the box, just looking at it -- I was less than impressed. But whoa!! That all changed the first time I used it! I have a 55 gallon planted goldfish tank that gets allot of light. And so stubborn algae on the glass has always been an big issue (Side note: I have been an aquariumist for over 37 years..... so I have seen and used allot of glass cleaners, including many magnet style ones.) Anyway, I opened the package and took it out and put it in the tank to use it Still thinking.... boy -- 39.00 seems like allot for this gizmo. ONE SWIPE. Yes folks... all it took just one swipe up and down the glass and I was hooked. One swipe up and down, using the "blade" side, took of almost ALL of the stubborn embedded algae that previously 10 min. of scrubbing had failed to remove. This scraper has an ingenious design- It has two little raised "bumps" on the blade side that make it press "nose down"on the glass at a VERY slight angle-- Thus causing the blade "nose" of the scraper press on the glass with a bit more force than the opposite end of the scraper. It is hard to describe this unusual little feature, but you will see it when you examine the unit. And I feel this adds greatly to its effectiveness because it works like a charm! Plus, the magnets held fast on the 55 gallon tank I was using it on. They are definitely NOT weak magnets. It has very strong magnets. Some other features are: It is two sided (Hence the name "Flipper") Flip it over from the blade side, and it also has the conventional "scrub pad" side that is perfect for removing slime algae and film. It also comes with an interchangeable plastic scraper blade to use instead of the metal blade. You would use this plastic scraper blade plexi and acrylic tanks. I was very pleased and would recommend this scraper. Yes, it is kind of expensive for basically some magnets encased in a plastic shell.... But you will easily get your moneys worth out of it just based on all the time you will save scraping your glass. It works very well! This is a good product. Cheers, Todd

Be very careful when cleaning near the gravel line. This little scraper/ scrubber has got to be the best product on the market for cleaning fish tank glass without getting your hands wet and with just one tool. However, I scratched my glass tank with this, I won’t say it was 100% the metal blade and could have been gravel. But I’ve heard that others say the metal can do that. I just couldn’t bring myself to return it as it works so well. I’ve tried gluing plastic home made slivers onto the blade to make my own plastic scraper and it works well, but it keeps falling off after scraping the tank a time or two, even when scoring the plastic and metal before gluing. I’ve decided to just use the soft side more often and be super careful with the metal blade only using it when necessary. I’m just surprised that flipper doesn’t make plastic blades for this product, it’s the only size that doesn’t get the plastic blade option. I may try 3d printing my own blades but I just don’t have the time to draw that up currently. Overall excellent design, and would be perfect if it had plastic blade options, yes even for glass tanks. Update: 2 months later I have since figured out that the scrubber was definitely responsible for scratching the glass as it traps sand. I don’t think the blade has caused any damage. Be careful with the scrubber side. I would only use the scraper for the bottom 1/2-1” of the glass near the sanded. Also, I have 1/4” glass and after a week the scraper wouldn’t remove a lot of the algae that had built up. It simply comes down to the magnet not being strong enough despite other peoples comments of these being too strong and that causing the blade to scratch glass. These blades if designed properly (round edges, which this has) don’t scratch intact glass if used properly. I bought the long tunze care magnet which has incredibly strong magnets. Enough to actually hurt you or break glass if not handled with care. Let me tell you, this magnet works wonders, unlike the square edged blade on this one theirs is slightly sharp and it works very well. Overall it’s a good product but I’d recommend getting a larger size than you need (for the added strength). Be very careful with the scrubber side. It’s a great day to day cleaner, but get a tunze care long magnet for getting the deep cleanings done. Those things push harder that most humans can maintain at an arms length for any time at all. I’ll never have to scrape the majority of my tank glass by hand again. They’re $50 on here btw.

Works great even on tough algae. Will be getting one for every tank we have. Well worth the money.

This thing cleans anything with one swipe. Even if it's caked on for some time. 10/10 must buy, even worked with my curved tank.

Its an ok product but my old fluval brand scraper seems to have done a markedly better job at algae removal

Excellent at removing the stubborn coraline algae on the glass! Very satisified
