I've included a picture that'll hopefully answer questions you may have. My attached spa is the same level as the pool and normally just flowed into the pool with bubbles. What I've noticed as I've switch to the TFPC method, my chlorine and MA additions weren't circulating which has given me brown spots in my plaster. I put my hand in the pool where the return jets are and noticed no flow because it's all dedicated to the spa portion. Today, I turned my valve halfway so both the pool and spa are circulating now, but the bubbles don't flow from the spa into the pool anymore. My question is, which is the correct way for proper circulation?
I get a LOT of direct sunlight and need to figure this out before I go broke from all the chlorine I'm buying lol.
I've marked my return jets with x's in the image below with a different angle.
