Q & A

Q: Will the replace the si-plus and is the cable included?

Asked by: Keith - 8/6/2017
A: Yes, the Si-45 cell is 100% compatible if you are replacing a "Si-45 Plus" version, same power, same physical size and connections, and it does include the cord. It should be plug and play to hook up. Just a tip: depending on the age of your controller, you may or may not need to change an electronic setting. Just give our support line a call and we can help you determine that.

Q: How often do you replace the cell of a salt water pool?

Asked by: Hayley Harris - 4/11/2020
A: It depends on which model you have, the size of your pool, and how you use it of course. But for this model I would say the average would be about 4-5 years.
