Our salt cell is done. We've had our system for 15 years. Its the Hayward with a t15 cell. Pool is 28,000 gallons. The prices of the cells right now are around $899 for Hayward or $500 for off brand. I can get a Circupool system for $1100. Should I go ahead and replace the entire system? Wondering if anything "new" has come out that would be beneficial to upgrade to? I don't want to pay the $1800 for a Hayward system right now - unless its better and worth it. But the control panel looks exactly the same. Is there a system available that I can read from an app on my phone - because that would be awesome! Thanks for any help! Its time to swim and I need to resolve this fast.
