Q:Will any sand filter work with this system or do i need a newer sand filter? Mine is almost 25 years old.
Asked by: Martin
- 6/26/2020
A:The CORE15 is designed to work with your existing equipment, so you don't typically need to replace anything else just because you are installing this. If your filter is old, cracked, or not doing a good job anymore, it is convenient to upgrade and replace it at the same time however.

Q:Hi there, I got some questions. does this unit shows a water temp?
also will this unit turn off when the pump goes off without being connected to the pump timer? in other words will it sense the water flow when the pump starts and come on?
Thankyou for your help.
Asked by: Nick Konstantinides
- 3/22/2021
A:This unit does not display the pool temperature. It's flow switch does activate/deactivate it with the pump's water flow. If you do have a timer for the pump, wiring them together for redundancy is ideal.

Q:Will this unit work for my 2200 gal pebble tec spa? Any special setting requirements since my spa much less than 15000 gal capacity of the CORE15?
Asked by: Ivan Lee
- 4/8/2021
A:As long as you can plumb it in, people do put small pool salt systems on spas, especially in heavy-use or public environments. You typically would want to put the salt system on its own timer that is set for a shorter run time than what the pump is run, so that you can easily make sure you don't over-chlorinate the water.

Q:I have a 11-12k gallon pool in DFW TX. Would the core 15 work for me? I only run my pump about 5 hours a day. Would this be long enough to create enough chlorine? What settings would I use? How often would I need to add salt to the pool?
Asked by: James
- 5/6/2021
A:Industry sizing recommendations are that your salt chlorinator has 1.5x to 2x the capacity of your pool, so you would likely want the next size up. More sizing information here. The settings are unique to your pool's use, climate, chemistry, etc... but once you get the system set up you do not usually need to make frequent adjustments to it. Salt is not used up during operation and doesn't evaporate, so after the initial install you only usually add salt seasonally to compensate for rain, splash-out, or draining of the pool.

Q:Will I have to add salt to the pool at installation? If so how much salt do I add to a 20,000 gal pool at the beginning
Asked by: Anthony Kaiser
- 5/12/2021
A:Salt chlorinators require about 3500ppm salinity in the water, so if there is not currently salt in the water, you'll add about 30lbs of salt for every 1000 gallons of water.

Q:Our pool has 6500 gal. and I think the CORE15 model should have the right size.
1. When do I have to change the cell for the first time? and
2. what means 8 years "limited"?
Thank you
Thomas
Asked by: Thomas
- 6/13/2021
A:Cell lifespan is dependent upon how its used and maintained. The system has a "cell life low" light that will help you know when you've reached that point. Salt systems have limited warranties since they reflect the fact that the cell is a consumable part. You can see the product's warranty information in the manual linked in the product description section.

Q:What is the face to face dimension for the water in-out ports. Looking to directly replace inline chlorinator if possible.
Asked by: Perry
- 6/29/2021
A:For this model, you cut approximately a 7" gap in the plumbing. You glue its unions on either side of the gap, then the system screws in place on to those unions.

Q:Can this be left to plug-in? The outlet at my pump box is not on the timer but the pump is on a timer. Or do I need to add a timer to the outlet?
Asked by: Steve
- 8/4/2021
A:When left plugged in to constant power, the system will activate/deactivate based on the flow switch. Powering a salt chlorinator & pump on a timer is even better, so that two redundant ways that they are being run in sync together; that could be either direct wiring it to a pump timer, or plugging it in to a timer that is set in sync with the pump.

Q:Does the unit stop making chlorine when the water temperature drops? My cold water light is on and it doesn't seem to be making any chlorine. If it stop, what is the temperature range for it to work?
Asked by: Richard Folk
- 2/15/2022
A:According to the manual, to protect the Cell, the Control Module is programmed to automatically decrease chlorine production when it senses low temperatures. In case of low water temperature below 64°F the unit reduces chlorine production to 50% and the LED below the 50% bar will be lit. Below 59°F the unit reduces chlorine production to 25% and the LED below the 25% bar will be lit. In both cases, the LED below the required level bar will be blinking and the "Cold Water" warning LED will be illuminated.

A:Everyone will get a different lifespan out of your cell, because you will use it more or less due to your pool's chlorination needs. This is based on your unique pool size, usage, environment, chemical balance, etc...
When sized appropriately, used and maintained properly, the cell can last many many years.

Q:How often does the electrolytic cell need to be replaced?
Asked by: Kevin
- 4/15/2022
A:Kevin, the cell lifespan is completely unique to your pool, depending on use, pool size, environment, water chemistry balance, etc... When sized correctly and maintained properly, you can expect many years of use, even past the warranty period potentially. The CORE model has an extended lifespan cell and other features that help provide as long of a service life as possible.

Q:Just plumbed in a Core35 but have not installed the module/cell yet and have a cover cap for circulating water while balancing. My cyanuric acid is high at 150ppm and tying to lower it with bio-active cyanuric acid remover down to your recommended level but not there yet and may take another week or longer. Have not added salt yet. Would you recommend going ahead and adding the salt and install the module/cell to start making the colorine prior to getting the cyanuric acid level completely down to the 60-80 ppm.
Thank you,
Perry Call
Asked by: Perry Call
- 5/19/2022
A:You can add the salt at any time, but as a tip it would be good to do it after you are sure that you will not need to drain any water (draining water would require adding more salt to compensate for what is lost). You could also install the salt system and just leave it off until there are proper salinity levels in the water.

A:If you are referring to "Low salt", you would want to ensure that the pool's salinity level is in range. If you are referring to "Cell life low", no action is immediately needed; the system is alerting you that based on your accumulated run time you are in the later stages of the system's lifespan.

Q:Hello, What is the minimum flow rate (GPM) for operation for the CircuPool Core series? I currently have a Jandy VSP pump that I run at 1200 rpms that generates 22 gpm. Would the Chlorinator work at this low flow rate? Thanks in advance for your assistance. Have a GREAT Day.
Regards, Eric Brown
Asked by: Eric Brown
- 7/10/2022
A:Flow rate and RPM's are part of the equation, but essentially a salt system's cell just needs to remain flooded with water during the operation of low pump speeds. 20-30 gpm is fairly typical for sufficient operation. Since this model's cell is clear, its easy to check if pump speed is too low and an air pocket forms, which would allow you to slightly adjust your pump's lowest speed accordingly.

Q:Are replacement cells readiiy available and how much$
If the flow valve breaks, can it be replaced or is a new cell required.
Asked by: Raymond Garber
- 8/10/2022
A:Yes, you can view the replacement cells under the "Replacement Parts >> Replacement Cells" area of site navigation. The cell itself contains the "paddle" that detects flow.
