is this open on both ends? or is it closed on one end?

Closed at one end, open at the other for the light to be inserted into the sleeve.

Will this work for the nova 1500 pool filter

This is a glass tube that the ultra violet light the Bulb sits in for a well water in your house. Not sure if it will work for you.

how often does this need to be replaced?

Cleaned once a year, replaced every 2-3 years. It will become cloudy over time and you can see when it needs to be replaced.

Two O rings included in the sleeve package. Have not yet installed or verified fit. Delivered unbroken though...that's a good thing.
