"I love this scraper."

This set really save me lots of time when I clean my aquarium. I have no idea how this would hold up to much larger tanks. The one hassle to this scraper is that mounting the blade can be very tricky. And i love that the handle is so long, I have a very deep tank. If you hate cleaning and scrubbing your tank this thing is for you. That has an impact on how well this brush works. Dont have to get wet, its very long, about 33 inches at maximum extension.

Tetra 77344 Final Thoughts

"Overall a great scraper."

5 gallon fluval EVO tank running a saltwater set up. The magnet is stronger and best of all it finally floats to the surface. So much better than any other ways I have tried. I would have gone to the next size up to get the extra pressure on the inside glass. Best aquarium cleaner if you ask me. One or two passes and glass was spotless. The long handle made it very easy to get everywhere.

"Still pretty good!"

It actually made cleaning the glass enjoyable. And I don't often say things like that. The sand cleaner accessory is cool, because it helps with routine cleanup. This is my second purchase of this scraper. I have a redsea 170 that is only about 35 gallons. My smaller aquarium has a back aside that the brush can easily clean. This scraper is a life saver for me.

"Not so with these!"

I found the key to keeping the algae under control is to clean the glass regularly. I still had to soak the hard to reach pieces in 1 part bleach, 5 parts water. Keeps my aquarium looking crystal clean. I found the key to keeping the algae under control is to clean the glass regularly. This mini magnet cleaner is really a great deal.

"Very pleased!"

But since no directions come, I thought I might mention it. The angled head of this thing makes all the difference. Easy to install the blade, seems to be well made. It's also significantly larger so cleaning takes less time. This is a nice tool to have is you have an aquarium. Guess how I learned that mistake lol. Everything is easy to put together and use.

Algae Free Final Thoughts

"Very easy to use."

There's another tool that I used to help reset the plants. I used a scrubber with little result. It's an easy to use pad that removed algae fairly easily from the acrylic. This little pad was just what was needed for cleaning up our 2 gallon bowl. If they had an extension that'd be nice. I have a 5-gallon fish tank with my beta in it. I have a 24 inch deep tank that requires I stand on a chair to get to the top.

Fluval 11024 First Impressions

"Very impressed."

It needs the extra support of the thicker pole. Nano magnet is a little weak on 6 mm WaterBox, but still works fine. How can a pandemic cause algae you ask. There are multiple attachments which gives options on what to clean with. So much better than any other ways I have tried. This is a good deal and perfect all in one package for cleaning aquariums. If it was half the size and maybe came with two extenders then it would be better.

Fluval 11024 Final Thoughts

"I couldn't resist."

The real bonus is it actually works. Since I knew this I am happy with it. Happy with the set and all the different interchangeable attachments. Due to the tank being built in, it's very difficult to clean from the back. It's also significantly larger so cleaning takes less time. I have a redsea 170 that is only about 35 gallons. It's an easy to use pad that removed algae fairly easily from the acrylic.

"Very sturdy."

The pipe cleaner attachment was very helpful in getting inside the UGF. Easy to install the blade, seems to be well made. Great for the price as I was not expecting something extremely heavy duty. I hand no issues with it scratching the glass. This scrapper will trap some of it making it easier to get out of the tank. Keeps my aquarium looking crystal clean. I bought this tool to help maintain my aquarium.

"This works great."

If you have an aquarium with algae, use razer to clean them off the glass. I bought this tool to help maintain my aquarium. It is way overkill for that small tank but I get the job done very quick. It needs the extra support of the thicker pole. This scrapper will trap some of it making it easier to get out of the tank. Don't bother with the other brands. You have to squeeze the ends and the cover slides off and the razor blade is exposed.

"You missed a spot!"

I have two aquariums, a 49 gallon tank and a 10 gallon tank. So that is the first tool head I grabbed was the corner cleaner. I have bigger fish and the net is for smaller. I could even clean the back glass by reaching over the top of the tank. How can a pandemic cause algae you ask. This is my second purchase of this scraper. I've used this tool a couple of times now cleaning the glass on my 125gal tank.
