Which Tank Siphon

I have a 36gal bowfront tank. I need a aquarium siphon to change the water and clean gravel but I am getting confused on the sizes.

 

I just use one size for my 10gallons, 20 gallon, 5 gallon and 2 gallon. I think I have the large top fin one? You could use the extra large though.

 

Get whatever you feel comfortable with. You could use a garden hose to siphon your water out if you want.

 

It's always good to get a siphon who's plastic tube is longer than the depth of your tank. This way you don't have to get your hand wet while vacuuming the tank. But...with that said, I can't say enough good things about a Python. I resisted getting one for the longest time, and then after I did get it I smacked myself in the head and said...WHY DID I WAIT SO LONG! It might just be the best invention ever!

A larger size will drain water more quickly, which is great if you want to get the job done fast or need to pull serious debris from gravel. A smaller size drains more slowly which might be a waste of time for some, but if you like to clean around decor it won't have as much suction so you can take your time and it won't drain the tank dry. It's also less likely to uproot plants or suck up small tank injabitants, and it's easier when working with sand.

I second the python! It is so easy, now I don't dread water change day like I used to, and definitely am better at keeping on schedule for water changes.

I kind of balked at the price on Amazon, but did a Google search and found it for $20 less on chewy.
