Hi, here's some pictures to make it (hopefully!) clearer -
This is the filter I have:

...and these are the 2 ends of it, so you can see what connections I need:

(this second one has a screw thread as you can see in the picture below this one)

...and this is the pipe I am trying to connect. (I have this pipe coming out of my pump via green push fit connectors).

If anyone can tell me what connectors I need to go on each end of my filter as shown above so I can attach this pipe I would be grateful.
If any supplier read this and can PM with a price inc postage I will order them ASAP as I need them for the weekend if possible :-)
Having recently noticed all the stuff floating around in my 25L containers (even thought my water still shows as between 3-5 TDS) I really need to get this sorted asap!
Thanks for the help guys
Steve
