Hello. I've had my pool and spa for a year now and the way it has been set up is with the pool return valve open to about 75% and the spa return to 25%. I run the spa spillway for 2 hours per day. When the spillway is off, there's always been water that comes from the spa return that spills over into the pool. I always wondered if that was ok, but negligently didn't bother inquiring about it. I probably still wouldn't be concerned about it, but the tile below the spillway has developed marks from the water that trickles down when the spillway is off.
I obviously can't do anything about the cosmetics of it because what's done is done. My questions are: 1) Whether or not that I should be concerned about what's going on behind the tile and 2) Should I adjust the pool return valve to 100% pool and 0% spa return? (since I normally run the spillway for 2 hours per day anyways and that should help with circulation) Thanks!
