Two Little Fishies ATLNM1 Nanomag Window Clean Device

Cleaning my tank has become easier and more fun with this gadget! Along with manual scrubbing, I've used mag floats for all my tanks in the past - from 5g to 50g glass and acrylic. In searching for a replacement for my 9g saltwater nano, I discovered two little fishies. Based on Amazon reviews, I gave it a try and am glad I did! Love it! Thanks reviewers!Like a previous reviewer mentioned, the other magnetic cleaners often came undone while cleaning with the in-tank piece quickly bobbing up to the surface. I have an open top tank so the bobbing and "popping" of the pieces back together often caused the critters slight distress along with small back splashes out of the tank (and onto my teak console table, ugh).The two fishes nanomag has a smaller footprint inside the tank than the smallest mag float, one of the few times when smaller is better! The in-tank side of the magnetized cleaner is just a little bigger than a postage stamp, a tad thicker than a quarter and semi-flexible. So it's great in a salt or planted tank where one no longer has to worry about the top of the cleaner bumping against live rock, corals or plants. These magnets are very strong and hold much better than my other mags. I can glide it easily throughout the tank without it coming apart and fit it to clean the glass between the nooks and crannies of my thermometer, cords, water pump and even the edges of the filter!I'm glad to see these improvements in the hobby to make cleaning easier and our fish/livestock happier!

There's not much to this mag cleaner. But I've found it to work really well.One nice thing about it is that it doesn't slosh the water around in the tank like the bigger mag cleaners will. So you can really work it back and forth easily.I have rock close to the glass and this is the only mag cleaner I've found that lets me get in between the rocks and the glass. For this it really works nice.It is also really nice to clean the curved glass corners.But I've got to order another one unfortunately. Oh, no not because it failed or anything... I had it in my tank and one of my kids pulled the outside magnet off and dropped the cleaning pad to the bottom of the tank. It doesn't float. So I saw it there and thought well I'll get it tonight when I do a water change.... WRONG... My Diamond Goby got hold of it and hid it in the tank somewhere. I can't find it anywhere. I think he must have taken it under a rock somewhere. So if the cleaning pad gets dropped to the bottom of your tank you might want to get it out instead of wait. :-)

It may be small, but this is a super powerful magnetic aquarium glass cleaner, which works great on both small and larger tanks. Because of the small surface it takes longer to clean my 50 gallon tank but it does a wonderful job. I especially like that the round outer magnet is easy to hold and the thin inner scraping pad is small enough to get behind live rocks, heater and filter tubes. I can not reach those places with my larger floating magnet scrapers, but I will still use the larger ones to clean the main glass of my larger tanks. I mainly use this Nanomag on my glass tanks as it will leave scratches on acrylic. I used it on one 5 gallon acrylic tank briefly and noticed it left some small scratches behind. I believe that this magnetic aquarium window cleaner is mainly meant for cleaning glass aquariums. I love how well it cleans, and this is my favorite algae cleaner by far! This was a personal retail purchase and I would definitely recommend it to others.

Works well but I have bought this a few times and the cleaning part does not last long.

This magnetic algae cleaner was just the ticket for the 4 gallon saltwater tank I have in my office. It's thin enough to reach even the tightest of clearances around live rock, but flexible enough to mold itself to the curved inside surface of the corners of the glass. The magnet is powerful and keeps the small scrubbing pad tight against glass to remove some of the most stubborn algae. I'm going to see if the have a similar product for my larger 30 gallon tank at home.UPDATE: 4/3/15 - Almost 2 years later, this product is dead. Apparently saltwater from my tank make it around the seal of the magnet compartment and corroded the metal magnet inside. This began to pollute the tank which caused an algae bloom which is what prompted me to examine everything in it and find the failed seal on the algae scrubber. It did a good job while it was alive and I may purchase again. If I do, I'll take care to dry it off after each use to reduce the chance of the same problem happening again.

I’m a huge fan of the two little fishes magnet. Been using it for 10 years, but when I wanted an upgrade & bought this product they gave me a tiny magnet scrubber less than half the size of the original. AND part of what made the original so good was the magnetic strength, this little shit will fly off the moment you start actually scrubbing. The only way to clean the glass with this product is if you go super slowly & anyone who deals with cleaning algae off glass knows that they just want to do the job quickly & efficiently.Don’t even sell this weak stuff. Get the proper sized scrubber!!
