We are building a pool ( our 1st ) in Houston. I am concerned about the water temp being too hot in late summer. I asked my pb about a chiller. He discouraged me from going that route. We will have 3 waterfalls and 2 jets and a bubbler on the tanning shelf. Will this help with the water temp or should we go with the chiller ? Should we install 4 jets instead of 2 ? I appreciate all your help. This forum has already taught me a lot !
