Hi - I bought a poolskim and I'm trying to replace some of the jets with the slot type. I managed to get the inlet eye out for the one I hooked the poolskim up to, but the other one is stuck. It's kind of an idiotic design and seems prone to the tabs breaking off.

Here is a picture:
I initially poked at it a bit with my fingernails and half the plastic tab broke. I then tried woth needle-nose pliers by opening them to fit the tabs and unscrewing. This worked for one, the other one is stuck because one of the tabs completely broke. Any suggestions to get this thing out?
