Carefree Fish Small Aquarium Gravel Cleaner Fish Tank 80Gph Water Changer Gravel Vacuum Adjustable Length ABS

I purchased the 40inch version and it's been great for my cleanings. I specifically wanted a gravel vac that allowed me to do quick cleanings without needing to always stick my arm into the aquarium. I use this primarily for a 29 gallon tank and also my 20 gallon long. I think the 20 gallon long use is best for quick water changes, the 40inch pulls water too fast from that size tank to be effective at cleaning the gravel.For the 29 gallon this has been perfect, good mix of being able to clean most of the gravel while quickly pulling water out of the tank for me. Best of all, I can do it without needing to always stick my arm into the tank thanks to the extension pieces they provide (length options for the plastic gravel vac 'arm' are: 22.4Inch~28.9Inch~35.4Inch).For someone with a 29gallon+ sized tankI think this is the only purchase you'll need. I've tested and used (way too) many gravel vacuums and this one has the best build quality, convenience (long output tube and configurable gravel vac length) while also being $25 which is similar to and cheaper than other products in this category.

I have a 3 gallon jar I use as an aquarium for shrimp, and this cleaner easily gets into all the nooks and crannies I need it to. Absolutely love how there is a pump to get the water to start.I do give this 4 out of 5 for two reasons: Although nice, the pump takes a bit to get going. And the second reason is the initial assembly is a bit more complicated than I initially anticipated. But, once the tubes are secured, you really only need to go through that once

Good quality for the price. Worked as I expected. Great flow rate. Great for my 10 gallon. Wouldn't use on something larger than 10 gallon.

I like the size of the vacuum and the length of the hose. The clip for holding the hose to the bucket is great. Suction is good. Would buy again.

This vacuum gravel has worked very well for me so far. I’ve used it for at least seven water changes, and have no complaints. In fact, the suction starts very easily, and I love the clip that keeps the hose on my bucket. I have a sand substrate and I am easily able to collect just what I want without suctioning up sand. I highly recommend.
