Magnetic Aquarium Fish Tank Glass Algae scrapers Glass Cleaner Scrubber Clean Brush [Floating,Scratch-Free,Non-Slip,magnetizing] S

Works great. Came as described. Have used it a few times and has a strong magnetic poll. Simple to clean. Easy to use. Strong.

This thing works REALLY well! It makes cleaning aquarium glass, even with a really thick coating of algae, very easy. I got the small one for my 3 gallon tank and it works great. Worth every penny!

I was looking for something small that could fit into tight corner of my aquarium and this little green guy seems to do the trick. Even though it states to use it on 0.35 inch (~0.8 cm) glass thickness or less, I actually use it on ~0.4 inch (1 cm). It works pretty well on scrapping off the algae on the glass, but you can feel it's not as strong as it should be. 2 things wish I knew before buying: First, it doesn't align with itself as you rotate the scrubbing around. Second, wished the description of the product stated that it was non-floating.

I'm absolutely thrilled with this magnetic aquarium fish tank glass algae scraper! As a proud owner of a beautiful goldfish aquarium, I was tired of struggling with stubborn algae stains on the glass walls of my tank. This product has been a total game-changer. The floating design makes it easy to maneuver, and the non-slip grip ensures I can scrub away without dropping it. The magnetic connection between the scrubber and the outside magnet is incredibly strong, allowing me to effortlessly clean the glass without having to touch the water or disturb my fish. The scratch-free material gives me peace of mind, knowing I won't damage my tank's glass. The algae comes off easily, and my tank looks crystal clear again. I've noticed a significant reduction in algae growth since using this scraper regularly. It's become an essential tool in my aquarium maintenance routine. Highly recommend!

It is very nice quality however the magnets are not very strong and drop apart easily.

This aquarium cleaner does exactly what it claims. It’s strong and effective in cleaning the aquarium walls with speed needed to get the job done in a timely fashion. The plastic material is hard and durable. Pretty color. Good value for the money.

WOW! This NEPTONION magnetic aquarium glass cleaner is magical! I used it to clean my fish tank glass walls that were covered with green stuff and I also, changed half the fish tank water. I noticed the water started to clear up! This product seems to be very well made and to last quite a while. I love the design. I like ergonomic, easy to use.

edit 6.2.24: I am sorry to have to reduce my rating down to one star. I'm using their largest magnet scraper on my 200 gallon tank to keep the algae at Bay and I can no longer do that because the razor blade scraper/holder won't stay seated on the end. it keeps on popping off. I've made sure the indent and tab are clean but nothing seems to help. edit 5.29.23 : ordered a new one after the other one started leaking. the new one has now been working for months with no issues so I'm upgrading my review to a 4 star. I'm withholding a star only because the first one was defective and I wish the magnet was a little bit stronger for my thicker glass. I have a 210 gallon aquarium and The Glass looks like it's about a half inch thick. this magnet scrubber seems to work great but in using it the first time I had a series of continuous bubbles emanating from the inside the aquarium half of the pair. strong magnetic attraction through the half inch glass seemed to work great on stubborn brown algae that has grown on the glass. some spots it took 10 or so passes of the inside scrubber to clean this stubborn algae off but I am pleased with the results. since my aquarium is about 2 ft deep the desire to have a floating magnet is key and my concern is the bubbles indicate water is going into the inside of the aquarium half. I may just have a manufacturing defect and will replace this unit for what I hope to be a better one from the same manufacturer.
