This filter has two different size hoses? I ordered off amazon and it didn't give any info on wich model 221 2213 2215 so I went with the 40g one and reading the back of the box it sais it runs two size hoses, I need 13mm hoses on both sides. I haven't opened it yet everyone's asleep, just kinda disappointed I guess now that I need to buy a seperate glass either inflow or outflow
