Attached spa return .. no cover?

[drain_the_swamp]

We have an attached spa sitting above our pool. It has a spillway feature where the overfilling comes down a fountain into the pool.

In Spa mode, there are 5-6 dedicated jets. These have proper plastic covers that can be adjusted, turned, closed, etc. I am surprised it took me this long to notice that this particular return does not have a cover. It is the sole return that is on when the pool and spa are in spillway mode, so this is the only return that just overfills the spa for the fountain when the spa isnt being used. I dont think it ever had one. All our other returns in the spa and pool have a cover but this one. As you can see the plaster goes into it and is the worst spot for mustard algae and a big pain (nearly impossible) to brush.

Is this normal for pool contractors to do?
If this was a miss by our contractors is it easy for me to just buy a plastic return cover and install it? Theres no thread on the pvc so I am not sure how I would do this.\

Sidenote- there are some cracks in the plaster there.. We plan to call our contractors to fix the issue after we see how much worse it gets. There has been worsening separation on our pool deck from settling.

Thanks

It looks like they cut that pipe a bit short which is why you don't have a return fitting screwed into it.

Even if you slide something into the pipe you can have algae growing around it.

I would leave it the way it is and get a small brush to hit around the pipe whenever you are in the spa.
