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.

Asked by: Michael Walls - 3/21/2021
A: Good question. No, just the consumable cell is replaced. You can see those cells here: https://www.circupool.com/CORE-Series-Replacement-Cells_c_53.html

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: which system should I use for a 24,000 gal pool?
