uxcell 61-Inch Aquarium Air Tube Hose Pipe Cleaning Brush - Long Flexible Fish Tank Accessory for Air Pump, Filter & Bubbler Maintenance

The brush sizes are perfect and the bendable wire helps get hard to get to places. The quality is extremely good. I had to wait for it to be shipped all the way from China, but it was worth the wait. Much better than anything at local pet or fish store (and I live in a big city).This is a great product for cleaning the tubes to my Canister filter. You wouldn't believe how much stuff it puts back into the water. The only problem with the tubes, is taking everything apart. You have to be careful not to have a bunch of water all over the place. But the brush does a great job of getting into tubes that are curved. Would recommend this to anyone.The bristles on this brush are super stiff! So stiff that I was unable to get it to push through the tube. Instead, the brush got stuck - and when I tried to pull it out, the brush stayed inside the tube w/ its end sticking out, while the main wire hose came loose from the brush. Thankfully, I was able to use a pliers to extract the brush that was stuck inside the end of the tube. The tube I was trying to clean was a standard size fountain tube. Couldn't believe how easily this tube brush broke!Works as it should, but was too big, thick for what I need in my tiny pipesI have a canister filter outside for my pond. But the hoses that it came with are a clear transparent type so algae grows like crazy in them. This brush has made cleaning those out SO MUCH EASIER!This long wire brush makes it easy to clean my tank canister tubing without all the fuss, they are extremely flexible and do a really good job.It does exactly what I hoped it would do. It cleans out the tubes in my aquarium to keep the water flowing smooth.ok for cleaning filter but will make the turn in tubes
