Python Gravel Cleaner, X-Large

I bought the mini version for my 25litre tank- it's a tall tank so siphoning the gravel isn't easy but it's not that difficult either and I wouldn't swap this size version for a bigger one.Since the tank is on a cabinet and above the bucket I siphon the dirty water into, i put the siphon head into the tank then suck the tube on the other side. as soon as the water starts coming down i put the tube into the bucket- it didn't take me long to get the hang of it.The tubing itself is made from exceptional quality- it's thick and strong.The siphon head doesn't have a lining to stop fish or shrimps getting picked up and trapped, but the 'neck'? of the plastic siphon is incredibly narrow and actually when siphoning the fish don't like to get near me anyway so i'm not worried they'll get hurt.One issue i do have though is if i don't pull the siphon up fast enough and too much gravel gets lifted up, occasionally bits of gravel will get sucked up too far. they then get stuck in the neck part of it and it stops the water flow. I then have to separate the tubing from the siphon head to release the bits of gravel and then reconnect them, and 9/10 times this will mean I have already broken the water flow and have to restart the process. This is my only issue and it's partly due to my own error anyway, so I would still buy it again if I needed to.One question I do have is that some parts of the tubing had originally gone a dark green colour, which I assumed was from me just forgetting to wash the inside with clean water. It now got a few PINK/RED patches, again on the inside, and this time I have no idea what's caused it. I don't have any red tinted plants in the tank. It may be bacteria, I don't know... but it hasn't gone yet. I'm not that bothered by it as I only use the siphon to take dirty water out and not fresh water. This is just something to bare in mind.Python is an exceptional brand and definitely worth the money. The mini version I bought is at a very reasonable price and cheaper than some of the other branded siphons that are also on sale on amazon and are not built nearly as well.This is a simple yet very effective product.

This is the only one you need, you can vacuum all your gravel without taking too much water out. I have 4 cheaper ones in the bin! Dont be like me and buy cheaper to save money, this is the best one out there!

Very good product for my 30L tank. This is the perfect proportion of suction and amount of water removed, I can remove most of the waste in the gravel without removing more then 10/15% of the total waste, that was exactly my objective. - bit tricky to get started, but with a bit of trial it’s fine. Definitely suggested for tanks of around 30L

This is a brilliant Syphon. However as a gravel cleaner it needs two modifications. The first is a Syphon starter bulb to avoid having to suck by mouth. The second is a valve to reduce the rate of flow which is too fast for effective gravel cleaning. With the modifications it cleans gravel very effectively in my 6ft tank.

I bought this gravel cleaner as a replacement for my old one as it broke.It is a brilliant little sucker! It a has a lot of suction power and is thin enough to get in the little nooks and crannys of the aquarium.It is easy enough to get started, just pop the thin tubing into a bucket, place the gravel cleaner into the aquarium at a horizontal position, let the gravel cleaner fill with water and tilt the gravel cleaner to a vertical position, once the water starts moving down the thin tubing it should start sucking through into your bucket.

Have kept fish for 15 years, and after taking a break from it, decided to set up a small tank for a siamese fighting fish. All our old syphons were to big for this small tank so bought this one. Great price, much cheaper than our local pet shop and works perfectly. Would recommend if you have a small tank

Quite disappointed really. I thought this was exactly what I was after as my other siphon is a bit large but its not great. Firstly the lack of a hand pump valve to get it started isn't great but not a deal breaker... unfortunately the suction is very poor meaning that while you can hit the area's you can't with a bigger model you can't actually clean properly.

Only recently bought our first 30 litre aquarium and have 6 zebra Danios. Needed something to help with the weekly cleaning and this is great. Good quality product and does the job. Not sure how it would cope with a larger tank though. However, would highly recommend this Python product.
