"Great magnetic strength."

My aquarium recently had a bad algae outbreak. This set comes with acouple different cleaning tools. It works great for my tank, you may want to get a bigger pad for larger tanks. 5 and a medium sized one for my 100 gallon reef tank. It actually made cleaning the glass enjoyable. I'm glad I purchase it as it also comes with a net. I bought this based on reviews and sure enough it took care of the algae with ease.

CNZ Final Thoughts

"I couldn't resist."

The head of the scrapper has no sharp or hard edges to scratch the glass. So much better than any other ways I have tried. It also works well at knocking off buildup from my decorations without removing them. The angled head of this thing makes all the difference. I bought this tool to help maintain my aquarium. It needs the extra support of the thicker pole. Just a great set of tools for the price.

"Great buy!"

This work well at cleaning the glass and is a great price. I have a fairly deep sand bed in my 90 gallon reef tank. Keeps my aquarium looking crystal clean. This cleaning tool set has been working wonderfully. I still had to soak the hard to reach pieces in 1 part bleach, 5 parts water. You don't need a lot of force, just patience. This scraper is a life saver for me.

Coralife (Energy Savers) Biocube Algae Cleaning Magnet Final Thoughts

"I will say this was 2-2."

I found the key to keeping the algae under control is to clean the glass regularly. If they had an extension that'd be nice. If you are too close to the top water will splash. This aquarium scraper is so much better than the old one. This set really save me lots of time when I clean my aquarium. This works significantly better than any handheld scraper I've ever owned. It is quite sturdy and made of stainless steel so it should last a long time.

It's designed nice, very solid and it's a decent price, what's not to like about it. I have a redsea 170 that is only about 35 gallons. This cleaning tool set has been working wonderfully.

"Very easy to use."

Add in a gravel vac and you'd basically have a complete cleaning kit. My only gripe is that the blade is not replaceable. Overall this was a very good purchase and good investment. I'm glad I purchase it as it also comes with a net. You have to squeeze the ends and the cover slides off and the razor blade is exposed. It actually made cleaning the glass enjoyable. A little more tomorrow and the next day and almost all the algae will be gone.

Just a great set of tools for the price. Overall this was a very good purchase and good investment. If it was half the size and maybe came with two extenders then it would be better.

This scraper is for an acrylic aquarium. For stubborn spots, you may need to scrub a bit harder. Cuts through built up algea in hard to reach places with no problems! Like the old kids toy dinosaur head that closes mouth by squeezing. But since no directions come, I thought I might mention it. One or two passes and glass was spotless. It works great for my tank, you may want to get a bigger pad for larger tanks.

"Awesome solution!"

This scraper is a life saver for me. It's an aquascape aquarium by the way. This set really save me lots of time when I clean my aquarium. And 23 inches roughly when its fully retracted. Small and inconspicuous in the tank. So much better than any other ways I have tried. The angled head of this thing makes all the difference.

"Wait for it."

If you are too close to the top water will splash. 5 and a medium sized one for my 100 gallon reef tank. I hand no issues with it scratching the glass. There's another tool that I used to help reset the plants. How can a pandemic cause algae you ask. Like the old kids toy dinosaur head that closes mouth by squeezing. And when i drain water out i can use this without getting wet.

"No scrub, scrub, scrub."

5 gallon fluval EVO tank running a saltwater set up. Interchangeable pads and a water release for the rod. There are two minor drawbacks to using this tool to scrape algae though. There are multiple attachments which gives options on what to clean with. If they had an extension that'd be nice. I've been recommending it to all my friends with aquariums. But this simple tool does the job with no chemicals.

That has an impact on how well this brush works. This works significantly better than any handheld scraper I've ever owned. And i love that the handle is so long, I have a very deep tank. And 23 inches roughly when its fully retracted. The one hassle to this scraper is that mounting the blade can be very tricky. So much better than any other ways I have tried. It is very handy for keeping my 30-gal freshwater aquarium clean.

"It is metal, after all."

That I haven't seen in any other tool set. You have to squeeze the ends and the cover slides off and the razor blade is exposed. This kit is great if you have pretty deep aquarium or shorter arms. It actually made cleaning the glass enjoyable. The rake came in handy to smooth the gravel after the gravel cleaning. Due to the tank being built in, it's very difficult to clean from the back. I was surprised at how heavy and well built this is.

I was surprised at how heavy and well built this is. It also works well at knocking off buildup from my decorations without removing them. This scraper is for an acrylic aquarium. Nano magnet is a little weak on 6 mm WaterBox, but still works fine. The pipe cleaner attachment was very helpful in getting inside the UGF. You don't need a lot of force, just patience. If it was half the size and maybe came with two extenders then it would be better.
