    Muriatic Acid

    I have a CAT4000 connected to a 50,000 gallon pool and a CAT2000 connected to a 2500 gallon hot tub. Both use acid feed to control pH. Do I need to dilute the acid before I feed it or can I use straight muriatic acid?

    I think the only reason you would need to dilute it is if you need a lower setting. Meaning, you have it on the lowest setting and it's still dispensing too much.

    It's an automatic dispenser. The system checks the readings every second. So it feeds until it reads that it's satisfied.

    Have you posed your question to the manufacturer?
