Thanks for all the responses. I think we might have found the possible leak.
On the spillover from the spa to the pool there are a few cracks. Any suggestions on the best way to repair the connection between the tile and pool wall at the spill over? Putty, grout, silicone?
You can see the cracking in the 2nd photo
