This is the Nano Mag by Two Little Fishies. Positives: Magnet is super strong and cleans easier than other magnetic cleaners, is flexible and cleans the curved glass areas found in all nano cube all-in-one style systems, and is only 1/8th inch thick and easily slips behind rock and corals close to the glass cleaning with ease. Negatives: the product feels like it may fall apart after long term use unlike other magnetic cleaners, it leaves a 3/8th inch uncleaned area next to the tank trim unless you pull the outer magnet off the glass and hold it half on the trim and half on the glass to force the inner cleaning magnet onto the uncleaned strip. The benefits of this product far outweigh the negatives and I'm sure future designs will address these issues. I give it 9 out of 10 this product is a must have for all nano reefers.

Everybody has his own technique for the cleaning the front glass of his aquarium. Some prefer new algae magnet cleaners while others stick to plastic scrapers. However, if you want everything easier and prefer to stay dry during cleaning your fish tank, an algae magnet cleaner is the solution.The one unique feature about this betta aquarium glass cleaner is that this particular make and model incorporates the wonderful feature of “flotation” in their design. As I said before, there are many of these kind of magnetic scrub brushes for fish tanks on the market, many of them don’t float if dropped. That can always pose a problem if not just a simple inconvenience. As the two devices are held together by magnets, if you were to separate the two pieces too far apart, the one on the inside of the aquarium would fall to the bottom. Not in these. If you separate these two scrubbers too far apart, the one on the inside of the aquarium will simply float to the surface so you can easily set it back in place without having to stick your hand all the way into the bottom of the tank to retrieve the fallen fish tank scrubber. Without having to gone to that hassle so many times, you may not really understand how convenient that is. I really have no idea why it took the aquarium industry so long to have the brilliant idea to incorporate flotation into these devices. All I know is that I am really glad that somebody finally did!The magnets can float in the water, so it will simply float to the surface of the tank where you can easily retrieve it. Simply turn the handle by a 90-degree angle and the two magnets will separate and you can easily remove them for cleaning and storage. If you have a glass fish tank and are finding a cheap and simple magnet cleaner for the tank, the Mag-Float cleaners are a great choice for you.You can find Mag-Float's here (affiliate):

This is my product review and demonstration of the Mag-Float Aquarium Cleaner for a glass aquarium. Please be advised that there are two variations of this cleaner, one for glass aquariums and one for acrylic aquariums. Additionally, please be warned that as this cleaning product has magnetic properties it will attract small magnetic iron particles that are in your aquarium and if not cleaned on occasion can scratch and damage the glass or acrylic. In my product demonstration I show you the functionality and efficiency of the mag float aquarium cleaner by cleaning the algae off the front of my fish tank that has accumulated over the course of several months. Additionally, I demonstrate how the mag float can float and how its magnetic properties allow you to easily traverse the corners of the aquarium. I plan to do a follow up review on the mag float after having used it for a few months.
