Aquarium Magnetic Algae scrapers

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.

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.

This works fairly well on light algae growth. I have to pass it over the same area several times to clean it completely. I think it is a little small for my 20 gallon tall but originally bought it for a smaller tank. The magnet is not strong enough to go around corners and will release if pulled out slightly but works ok. I have sand substrate and it will get in between the cleaning block and the glass if I touch bottom. I mainly use it on the front of my tank. I ended up buying a razor cleaner for the sides and back to take care of what the snails don’t. I continue to give them a chance to do their job but 🤷🏼‍♀️. I also use it to get the very bottom edge along the substrate.

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.

Fabulous item! I luv it!! My water looked fine on the inside but the algae on the glass made the tank look terrible I thought the fish were living in horrible conditions until I bought this product and used it. In one swipe it cleaned it up to look completely clear and my fish are fine! I don’t know how long it will stay working this good but at the price I’ll toss it and buy a new one. My kids also love being able to clean the glass. My only regret was not taking before and after shots to show the difference.

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.

Neptonion ist super, reinigt die Scheiben am Aquarium echt sauber.

60センチ水槽で使うのはデカすぎる。 そして磁石が強すぎてケガする。 キレイにはなりますが、気になる部分のほうが大きいです。

Es una excelente opción para limpiar las peceras grandes. No se cae el limpiador y limpia de lo mejor. Altamente recomendada!

This works well to keep my glass clean without scratching

Molto funzionale
