Intex sand filter discharge reducer fitting

[Poconos]

That 2.25" you measure is really a 2" pipe thread. The discharge hose is probably 1.5" so you will probably want a 2" female thread to 1.5" barbed adapter. The dark gray plastic ones for the black poly pipe. You can heat that blue hose to stretch it if necessary then throw a hose clamp on it. I found that when working with pool hoses an electric heat gun is a valuable tool. They're cheap and used for stripping paint. Just a side note, at both Home Depot and Lowes it seems like people love to put things back in the wrong bins. You gotta root sometimes. Drives me nuts.
Hope this helps.
