Okay, so there is two hoses for a canister. One takes in water and one pushes out water. Well, this isnt the case for me. I opened the box and found only one hose! What do I do?! Should I return it or buy a hose online?
Don't worry!
If you read the instructions, you'll see that it says you have to cut the hose in two to suit the length that you need. Read over the instructions, because if you cut it incorrectly, you may end up with one piece that's too long and another that's too short.
If you can't find tubing at the LFS, try one of the hoses that comes with gravel vacs. I found the larger gravel vacs have just the right diameter hose for my UV sterilizer I am trying to use.
