Hi, I have enjoyed lurking here and got a lot of helpful info in my spa hunt. We decided on the giant Paradise model of LA SPAs (11x8). My 8 year old PDC Aruba (7x7 325 gallons) is going to my sisters house. My dealer says that I have to have our amp switch (outside cutoff) changed from 50 to 60. My question is: What should my sister have put in for the Aruba coming to her house?? Was 50 strong enough for the Aruba? Thank you for ANYONE with any input! Happy Holidays, Victoria PS We have a big family so we needed a BIG hot tub.
