My Aquario Cone only came with a suction cup and I was annoyed that the tube was bent. I used suction cups to make sure the tube goes straight up. The suction hoses were cleaner than my CO2 kit hoses and filter canisters which were a bit frosty. So I also replaced my Lily Pipe and Filter suction cups with these. You can even remove the rings if you want the hose to fit wider inserts. Very cheap and functional for what you get!
