Either hydrochloric or sulfuric acid is fine for adjusting the pH of the RO feed water. Most people prefer sulfuric acid due to the corrosiveness and fumes from hydrochloric acid.
Its probably best to dilute the HCl to reduce fuming, and to have good ventilation in the room where the feed tank is.

You can replace no problems but in DI Units only
