Question: The system looks cool! However, All of my research points to the fact that if I use a CO2 system such as yours that I'll still need to add muriatic acid to control the rise in Alkalinity? Is this true and if so what is the benefit of this system if I'm still going to need to add muriatic acid weekly to maintain proper alkalinity? My pool is 18K gallons for reference. Can you please help to clarify?
