I order one neck extension model NK-250 from an online store. It stated NK-250. I order it for my SRO-XP5000int, my skimmer work great but I want to improve it so it can run optimal. When I received it, the NK-250 is smaller than my skimmer neck. Can you help to explain why it smaller than my skimmer neck? Thank you.
