I am hoping someone has some insight on my salt water situation. We have a 7 year old, in-ground, dark gunite pool around 40,000 gallons. We use the Aqua Pure 1400 system along with the Aqua Link RS keypad inside. We had an issue with our sensor so we ordered a new one and then our aqua pure system completely died over the weekend. We think some rain water might have gotten into the unit. Anyhow, we are at the point where we are deciding what to do next. Over the last few years I feel like the unit has been nothing but costly and providing very little benefit. We do have an automatic chlorinator that takes 1" tabs as well. I have considered eliminating the salt system entirely, utilizing the automatic tab chlorinator, and adding Pool Proof. I wanted to know if this would be a viable alternative or if we are stuck purchasing a new salt unit. If we need to purchase a new salt system, to be compatible with our RS keypad, does it need to be a new aqua pure system? If not is there a better unit on the market that we should consider? Thanks in advance for any help!
