PythonPro-Clean Aquarium Gravel Washer & Siphon Kit, Mini

The best flow rate for deep cleaning substrate.Keep in mind this product is significantly smaller diameter than the vast majority of comparable items. It is also 3× as long.The combination of its length and smaller diameter make it draw water much slower. The hose is also a fall smaller diameter as well. So definitely not your best option for a fast water change.However where this vac shines is in its flow rate. I can do a 50% water removal in my 37 gallon tall and still be able to get 95% of the substrate cleaned. That is a game changer for me.I love this Python 😀. I mean..I have always loved all my Python products over the years. But this one is my new favorite.I am like a gravel vac sniper but at a snails pace. It is slow.Another perk I want to mention is that it's really effective at picking up a large amount of substrate and transferring it to a different area of the tank. This was very handy at covering some exposed roots I had.Also it consolidated snails. Not strong enough to suck them out, but you can get them all into one area and them trap them!Giving this one the rare 5th ⭐️.

I have tried several of these, and this one is my favorite. It's small, yes, but I need the small tube to get in-between plants. The hose is nice and flexible, and the long length is much easier to use (keeps your hands out of the water). It does make it a bit harder to start siphon, but that's not the products fault (I just suck on the tube, I don't care). I do wish these came with longer hoses though, It would be nice to have a bit more hose sometimes.

Works great for cleaning fine sand bed in saltwater reef aquarium.

Just what you need for water changesLong enough for 18in tank

The last Python I bought was 20 years old and still worked well before I stepped on it. It's the perfect diameter and length for my 50 gallon reef tank. The smaller diameter is ideal in that its not overpowered like some and helps it fit into the smaller nooks and crannies. The hose length is generous and kink free.

Love it

The suction is horrible

Bought this for my TF 36 gallon bow front tank. The tank is pretty high/deep and has sand. This worked perfectly for this setup and I couldn’t be happier. I can siphon without getting my hands in the water and it cleans the sand great.
