Excellent question! The CORE CONTROL can be used in conjunction with either acid injection or CO2 infusion, and since these pH control strategies operate differently their implementation is different as well. Here are the two options for pH control in detail:
Both options are a completely effective way to make pH balance much more of a "hands off" issue. If you'd like to eliminate the need to buy, store, handle, and use of liquid acid - using the TOTALBalance is the optimal choice, and the CORE CONTROL's pH sensor makes it even more convenient and adds remote monitoring. If you'd like to fully automate your pH so that you always ensure balance in response to changing needs, the CORE CONTROL's complete Balance Control upgrade kit is the choice to achieve this. Please be sure to let us know what other questions you might have.
- Automatic pH control using CO2 infusion:
- CO2 infusion requires steady, regular addition of small amounts of CO2 every day - this achieves a saturation point that allows for pH to stabilize at an optimal level with minimal CO2 addition required to maintain a controlled balance over time.
- For this you would choose the CircuPool TOTALBalance and use it with the CORE CONTROL + basic Balance Control upgrade kit with ORP sensor and pH sensor. This allows you to have the benefits of a controlled stable pH without the use of acid, while being able to remotely monitor the water's pH level and get automatic alerts if your attention is required.
- Example: After installing the TOTALBalance with the infusion setting recommended by the sizing chart, you let the system run for a couple days and notice in the CORE CONTROL's app that its pH sensor is detecting that the pool water's pH level has stabilized at about 7.6. While in range, you'd like to achieve an ideal 7.5 level, so you slightly adjust the TOTALBalance's infusion setting, and see that afterwards in the app that the pH is staying at 7.5 every day. After a few months, things have gotten "out of sight, out of mind" and the TOTALBalance CO2 tank gets low - you then get an automatic alert in the app that the pH level has climbed out of your preferred range. You swap your CO2 tank and the system resumes operation, and the pH level gets back in range.
- Automated pH control using acid injection:
- Acid injection is a powerful way to adjust pH level, so it requires the use of a pH sensor which controls when acid gets dosed into the pool, in response to changes detected in the pool's pH balance.
- For this you would choose the CORE CONTROL + complete Balance Control upgrade kit with ORP sensor / pH sensor plus acid pump and acid tank (if not supplying your own). This allows you to control pH on demand, remotely monitor the water's pH level and get automatic alerts if your attention is required. Additionally, the CORE CONTROL can be set to periodically dose a small amount of acid into the cell when the pump is not flowing, to help prevent scale formation.
- Example: After installing the complete Balance Control upgrade kit, the pH sensor detects that the water's balance is higher than the preferred range you've set, so it begins to slowly dose acid into the pool until pH is within range. After this, acid injection ceases until the next time that the pH sensor detects that pH has climbed out of range. The pool water's pH level stays correct every day, and later in the season you get an alert in your app to check your acid tank's level. You confirm your acid tank is empty, refill it, and the system resumes operation and the pH level gets back in range.
Both options are a completely effective way to make pH balance much more of a "hands off" issue.
