I have a pool that is about 10,000 gallons but I am thinking of buying a salt chlorine system for pools up to 20,000 gallons. Would the larger unit be a problem?

It is not a problem to oversize a salt system. It would take the larger unit less time to produce the necessary chlorine so it is actually more efficient. When the pool volume is very close to the capacity of the salt chlorine generator (for example, the pool is 18,000 gallons and the generator is rated at a maximum of 20,000 gallons), we would recommend going up to the next size generator.

Is the salt included with the salt chlorine generator?

No, salt is not included. You would purchase the salt locally and the quantity will depend upon the number of gallons of water in your pool. Use a salt that is at least 99.8% pure NaCl. The preferred salt is evaporated, granulated, food quality, and NON-iodized. Avoid using salt with anti-caking agents like sodium ferrocyanide, also known as yellow YPS (prussiate of soda). These cause some discoloration of fittings and pool surface finishes. DO NOT use calcium chloride.

why are some models recommended for above ground pools. What are the design differences between a chlorinator model for in ground pools and the above ground models?

Hello Don- The key difference is this system is that it is an 115v system and comes with an external power supply that would plug into a regular outlet where are the in-ground systems would connect directly to a breaker.

Do I need to purchase any type of control unit when I purchase this or is this everything I would need for a new pool installation?

Hi, Steve. This system includes everything for the installation.

Why can’t I buy this without the electrical box?

How do you tell when the cell needs replaced

Generally, most cells have a lifespan of about 3-5 years of continuous usage (every day). Once the system no longer producing chlorine, that might indicate that your cell is bad. Unfortunately, we do not have any information from the manufacturer which would suggest there is a DIY test for making sure the cell is still good. I might reach out to Pentair directly to see if they have any advice. They can be reached at 800.831.7133
