If my pool is 15,000 gallons, give me the recommended size salt chlorinator
CORE Series
The standard rule of thumb is to size a salt chlorinator at 1.5 or more times the actual pool volume in gallons, while 2 or more times is appropriate in warmer southern locations. Since you are asking about CircuPool's CORE system, then the answer is to use a CORE 35 regardless of where you live. However, over-sizing further can result in longer term cost savings as the more powerful CORE 55 operates at a lower output which extends the life of the salt cell. At everyday prices, a CORE 55 might cost you about 14% more than the 35, but it is capable of producing over 40% more chlorine over its lifespan and consequently extending the life of the cell.
