I had a problem with getting this working. I called the 888 # and the man helped me get it setup. Now it is working fine. The last one was 6 yrs old . I hope this one lasts as long.

Replacement Cell Swap

Purchased this Si-45 replacement cell, when my 5 yr old DIY installed CircuPool Universal Si-45 system starting showing signs of cell degradation - lower than normal chlorine output & salinity readings dropping and not matching actual pool salinity.Ordered new Si-45 cell from CircuPool site, and it arrived quickly.Swap was straight forward, plug n play. New cell working as expected with chlorine output, and salinity readings now closely matching actual.

Q: I currently own a Circu-pool Si series chlorine generator,. The current cell is a Si30 that has a maximum output to sustain a 30,000 gal pool. I have a 28,000 gal pool. The cell is in need to be replaced. Can I replace the Si 30 cell with a Si 45 cell?

Asked by: S.J. - 6/1/2019

A: Yes, that would be compatible and would well worth it. You would just change the cell type to "f-15" on the controls.

Q: I need to replace my cell and can't find the model number. The cell is the Si series but I ma not sure if it is the 45 or the 30. My pool is a final liner 15x30 deep end 15 feet shallow end 3 feet. I live in South Florida. What would you recommend?

Asked by: Ashley Ron Comcast - 6/3/2019

A: You could likely get by with the Si-30, but the price difference is pretty small and you'll get much more for your money with the Si-45 and have a better experience.
