To keep things simple, we have just one price for residential pools. Our chemical subscription is sized for average residential pools, which are about 20,000-25,000 gallons. The majority of our customers are within that.
We have many who have larger pools, but they are used to paying more for chemicals, and understand that they will likely use more than an average pool. Other factors could cause you to go over the amount of chemicals included in the basic subscription, such as a very high number of swimmers compared to what we expect in a residential pool, or if the pool had pre-existing conditions and wasn't fully balanced at the start of the subscription.
If you start to need more chemicals, we'll reach out to you to discuss options.
