Great/plus update
When doing a water changed I noticed how much debris came up and I would pour the water out of the gravel so I decided to order this the 5ft-s after ordering it cam in 2 days and it does a great job of vacuuming the debris out of my gravel for reference I have a 5 gallon fish tank and this worked wonderfully to note you will have to pump a few times to get the water running, but the water does come out fast, but the water will only come out when it’s facing downwards not when it is facing up but when it started to run fast, I just stopped it with my finger, but it did a fabulous job with the debris sometimes because I take breaks between dumping out the water the siphon I did have to pump a few more times to get it running again, but it worked really great and I got all the debris out. It sucked up the debris wonderfully. Also, it is so easy to assemble just to make sure with the ball that you squeeze, you have it in the tube the right way or it will be a pain to get out but that was my fault for not reading the instructions correctly. The clip worked great against my tank and the 5FT – S was perfect for my size aquarium. One more thing for the people that have live plants. It did not suck up the gravel or mess up the way my plants were planted in my tank. UPDATE: it’s been 3 weeks and I have used it twice and it has worked good. The ball siphon was being annoying once for a little but now it is good.

Works very well and with ease
Perfect for quick water changes, easy to use, nice suction ability-self starting with just a few pumps of the bulb. Easy to clean.

Good siphon for fish poo
Definitely works well at removing water and debris but not that good at re filling your tank sense it works off gravity, good price for an easy to use siphon to get rid of fish poo.

Simple Design That Works Well
This siphon vacuum has made cleaning my fish tank much faster. The 5ft hose gives plenty of reach without making a mess. It does a great job pulling debris out of the gravel while leaving the gravel itself behind. Suction is strong and consistent once it gets going. Definitely takes the hassle out of routine tank maintenance.

Simple and Easy
Very simple and easy to use. Works as intended. I didn't have a bucket to use so I used a plastic storage tote and the clip fit perfectly on the side of it. I think this will be an essential item for any aquarium.

Good for 10+ gallon tanks, won’t work for anything less than that.
The product works well for my larger fish tanks but not so great for the smaller ones that are 10 gallons or less. It was easy to assemble and does not leak but it can be difficult to get water out of the tube once it is in there. So after a cleaning you may just have some nasty water sitting in the tube until next cleaning. It picks up sand well so in my tank that had sand substrate it would pick up that but not the waste because the fish waste was larger than the sand. It’s a bit difficult to clean but other than that I have no real problems with it. I would say if you have smaller fish that are not major waste producers and if you are okay losing a bit of the sand substrate (if you have sand) then this product is worth it and good for a beginner fish tank owner/keeper. But I would advise against getting it for smaller tanks because it will not work as well and may not work at all.

This product is life-changing! From someone who owns amazing turtles, their tank maintenance could be hectic. This has completely changed the maintenance game for me. While reducing the struggle to deposit loads of water in a separate bucket, no longer have to struggle with this new amazing device. User-friendly, beginner, friendly, easy to construct and deconstruct. Such an easy way to go about cleaning your pets tank. Time effective as it reduces the physical labor to remove water from the tank. I now can enjoy this process of cleaning my tank for my amazing babies. Without a doubt, for this amazing price, you will not regret this if you’re looking for an easier way to maintain your aquatic pets habitat
