No products found.
Kicking off our list with a highly popular product, the Mag-Float Glass Aquarium Cleaner from Gulfstream Tropical has earned hundreds of positive reviews thanks to its reliability and simple operation.
This magnetic cleaner is manufactured in the United States where the soft cleaning part is made of cotton material to avoid scratching your tank. The Mag-Float Glass Cleaner is suitable for all kinds of glass aquariums, but you should avoid using it on plastic and acrylic tanks since it’ll most likely leave unattractive marks behind.
The Mag-Float, as you can guess from its name, is engineered to float on your tank’s water when it’s not attached to the outer magnet. It applies buoyancy principles to rise up the water if you were to accidentally drop it, so you can easily take it out.
The Mag-Float utilizes strong magnetic forces to keep the cleaner parts stuck tightly, providing a smooth sail without sinking. The brush itself doesn’t collect sand or gravel which helps keep your tank walls scratch-free. However, you shouldn’t use this cleaner near electronic devices such as pacemakers and computers.
The Gulfstream Tropical Magnetic Glass Cleaner is available in 3 sizes to fit a range of tanks. The small Mag-Float works for aquariums up to 30 gallons with wall thickness up to 3/16 inches, the medium size suits aquariums up to 125 gallons with ⅜ inches thick walls, and the large scrape is fit for 350-gallon aquariums with walls up to ⅝ inches thick.

Why Should You Buy an Aquarium Glass Cleaner and Algae Scraper?
Cleaning the exterior of your tank walls is a straightforward task, but the interior side is where the real challenge begins.
A lot can happen on the inner surface of the walls of your aquarium, the two major events being algae build-up and hard water residue accumulation.
The build-up of algae is often the result of excessive plant stimulation by favorable conditions present inside the tank, such as constant exposure to light as well as nutrients that are readily available in the water, leading to exaggerated growth.
As for hard water residue accumulation, it’s mainly related to the heavy presence of minerals within your water supply. Granted, treating the water can certainly help decrease the severity of the problem, however, it doesn’t compete eradicate the issue. Also, some fish species actually require a mineral-rich environment.
Both algae and mineral build-up can cause your tank to look clouded and unkempt, blocking the view of your beautiful fish and marine plants. Of course, you’ll need to remove such dirt and residue, which is where glass cleaners and algae scrapers come in!
These tools are a terrific solution for cleaning the inner walls of your aquarium, removing algae and mineral residue to give you back the clear appearance of your hard work.
After reviewing dozens of aquarium cleaners and scrapers available on the market, we can divide them into 2 major types:

Magnetic cleaners are by far the most popular choice of fish keepers among amateurs and experienced fishkeepers alike, thanks to its incredible ease of use.
The concept of this type of cleaners is pretty simple. A magnetic cleaner consists of 2 parts, both have strong magnets integrated into their structure.
The outer piece is placed on the exterior of the tank’s wall and it usually has some sort of a handle or a grip for you to grab onto. The other piece is positioned on the inner side of the wall where it attaches to the outer part using a magnetic force.
Think of magnetic cleaners as burger buns and the aquarium wall is their pattie!
This type of cleaners saves you effort, time, and keeps you from getting all wet trying to clean your aquarium. However, if the magnet is too weak causing the inner piece to detach or you accidentally drop it in the tank, you’ll have to deal with the hassle of fishing it out.
That being said, most magnetic cleaners use a floating feature to help you retrieve any fallen pieces with minimal inconvenience.
Blades and scrapers require a more “manual” approach to cleaning. Typically, you’d be provided with a pad, scraper, or blade, then you proceed to swipe it across the inner walls of the tank while applying adequate pressure to scrub off algae build-up.
This type gives you much more control over the pace and intensity of cleaning than its magnetic competitor. It also does a better job removing stubborn algae since it delivers a tougher performance.
That being said, blades and scrapers are usually very sharp, so you may end up harming your fish or plants if you’re not careful. Moreover, the cleaning process can get quite messy, splashing water everywhere if the scraper handle is too short.
When shopping for the best aquarium glass cleaner and algae scraper, these are some important aspects you need to take into account before making a purchase. The 2 most critical ones are the tank’s material and size.
The first thing you should be looking at is the material used in making your aquarium walls. Why? Well, because not all cleaners and scrapers are designed to accommodate every wall material out there.
In fact, each tank material calls for a different cleaner type to provide optimum cleanliness and to avoid leaving scratches and marks all over the walls.
For example, stainless steel blades are more suitable for glass tanks and can’t be used for acrylic ones. On the other hand, ABS scrapers are compatible with acrylic aquariums but not with ones made of glass.
If you were to mix it up, you’ll just end up with ruined tank walls that are still dirty.
Following your tank’s material, you need to carefully check its size so that you can pick a cleaner with a proper fit.
The best way to achieve this is by selecting the cleaner size according to the thickness of your aquarium’s walls. This provides you with high precision when making a purchase to guarantee a correct fit, which is crucial to accomplish satisfactory cleanliness.
