Marina Easy Clean Mini Aquarium Gravel Cleaner 25cm (10")

So easy to use, I watched a quick video on YouTube and never had a problem

Does the job well. A little tricky to get going sometimes, especially perhaps in a smaller tank. Occasionally sucks up gravel and gets clogged.Suction power is pretty good!

This makes cleaning gravel so easy and also takes water out of the tank at the same time. Saves so much time and effort. Highly recommend.I see some reviews from people struggling to use this. Search for a video titled: How To Properly Gravel Vacuum a Fish Tank (Detailed Version). A very education explanation that will make using this product so easy.

This is for the mini version, which I bought to get to little nooks and crannies in my very heavily planted 87 litre tank.It’s useless - straight on the first try if you use it to dig around the gravel it sucks it straight up to the gravel guard and clogs the flow. I have medium sized gravel mixed with coarse sand. It seems the problem is that with the mini version is that the narrowness of the tubing causes the siphoning effect to be too strong, thus sucking up gravel due to the water pressure. The fact that there is no wider opening at the bottom adds to this problem.If you have sand, forget about it - the suction is too strong and it will it straight up and into your bucket.Stopped using it after two minutes and returned it.

It’s good but we have quite a small fish tank (15 litres) and even though it says it’s for mini tanks, it was still a bit too big. So I cut some of the tube down. It takes some getting used to and I’d recommend you watch a how to video on utube and practice with water that hasn’t got any fish in so you get the technique right. But once you do it’s really effective.

Seems to be a lot of fuss over using aquarium vacs but having used a traditional device like this I went with the same design. The shake up and down to start the flow works fine. The suction is just right for my 45l tank. No issues with gravel getting stuck. The tube is long enough too. Perfect.

I couldn’t get this to start by shaking it as per the instructions. So having read some reviews (which admittedly I should have done before I ordered it) I ended up sucking the end and having to drink some manky tank water. Nice.The other issue is that the filter is at the top of the tube, not at the bottom like the last gravel hoover I had. This means the stones/ leaves etc go up into the tube and are very awkward to clean out.Terrible product.
