two months ago I bought a house with a pool and I'm now a pool owner for the first time. My son killed the Jandy PDA by putting it under water too many times. I see there is a Zodiac iAqualink app for the iPhone. Can I set that up to run my pool or do I have to buy some kind of electronic devices to get it to work? If so what is the price compared to the new PDA for about $300.00.
