Wow, reading what you wrote I thought you were aware. However, you cannot change the entire mechanics of an aquarium to give one part a bad finish and you are probably not used to it due to the size of most pumps. It must match the pump hose. I assume you sell them together to get everyone's attention on the price because that's the only way you can sell those bad 1 inch tine parts. The barb must not be larger than the hose.
