Would you say this filter would be safe to use in a reef tank?

I am trying to put this filter in a 5 gallon bucket to polish the tank water, This filter is originally made for filtering oil

Welcome aboard!

The filter seems very fine, would not take much time to clog imo. Filter socks or media cup with floss https://www.saltwateraquarium.com/4...KT9oRKG8gQ9--f6AttgLJ2oYubelVDihoCVcYQAvD_BwE would be easier to maintain.

Agree with @Gareth elliott ....materials (HDPE and Nylon) are reef safe, but a filter sock would provide much larger surface area, allowing faster filtering. I'd suggest a 7 inch mesh sock....mesh socks are easily cleaned by running under a faucet while rubbing fabric to fabric. Also come in various micron sizes.

For polishing would go 100 micron, but it may clog quickly.
200 micron will clog less but polish less too.
Those 2 micron sizes are pretty much what’s available in filter socks.
Thank for sharing, never saw those

The filter won't take long to clog, and when it does, if that sits on top of the bucket, it will overflow onto the floor. I've also used filter cups and not a fan. In a filter cup the filter surface area is only the diameter of the cup since the holes are in the bottom. With a filter sock, all surface area of the entire sock filters out debris. So as the first inch clogs the water rises up to the next inch of sock and so on. JMO

For polishing water you want to use a DE filter.

Agree with some of the other comments, especially that if it clogs you'd need to worry about where the water goes. But besides that, those look like they might be pretty good for straining live food cultures, (e.g. copepods), cheaper than some of the screens I have seen marketed specifically to the aquaculture industry.
