Hi Tricia, welcome to the forum!
Gee, I'm afraid I don't even know where to begin in your scenario. The pool is built and done, so if there is anything to be done now I would imagine that would be quite the discussion between you and the builder - who by the way should've taken several factors into consideration. Unlike many who have a $30-$70K pool, your's is substantial which is another issue. I guess I'll start with these comments:
- Surface water movement is important as we would like for the jets to push surface debris to the skimmer(s). It's not always a perfect scenario though. Sometimes because of the pool design, other times because a pool was built in such a way it fights the prevailing wind direction, so the stuff on the surface is always at the other end of the pool opposite the skimmer(s).
- To test your water circulation, you might consider grabbing some packing peanuts or ping pong balls and toss them on the water. Hopefully when the wind isn't too strong, just to see where they go. Check your return jet nozzles. Hopefully they are the type that can be rotated a bit to angle the direction of flow. If not, talk to your builder about the issue to see if other nozzles can be installed to help with that circulation. They should be receptive as it's inexpensive compared to the alternative - redesigning the pool.
- For the spa & pool, generally we advise minimizing spillover from the spa as it tends to drive-up the pH quickly (aeration) which is not good for a pool, especially a new plaster pool that is curing for months. So unless you're using it or simply exchanging water in the spa for chlorine movement (change-out) and sanitation, see if there's a way to keep spillover off.
I hope some of this is helpful. Feel free to post back with comments, questions, or even to post a pic of your pool and the situation. Maybe that will prompt more replies.
