First Winter Test

[iain42]

Too early to prep for spring lol... Yeah I am jumping the gun with arkansas weather you never know what is going to happen could swim in march or april... I've kept my pool clean and open during the winter I like to watch my pool in the mornings with coffee or nights with a gnt.

FC 9.8 I turned of SWG in December 7th
PH 7.4
TA 40 will boost to around 70 next week
CH 370
CYA 40 it did measure 40 did it twice.
Water Temp 51

I have not surviced the SWG and we got it in April. I'll have to read up on that. Is there any reason I shouldn't trust these readings?

Leave it all alone. Looks good.

No real reason to 'service' the IC40. As long as you are not getting lots of flakes of calcium from the returns all is good. Keep CSI between 0 and -0.3.

Thanks
Ok CSI is new to me. Saw it available on the app in October so included it.
Got a FAQ for CSI ?

 

[iain42]

CSI reads -1.0 so I went ahead and made changes.
The changes I made today for TA and CYA should bring CSI to 0.63.

Calcium Saturation Index (CSI)

A CSI of 0.63 is in the scaling region. Be sure to get that to between 0 and -0.3 for your SWCG.

Almost there will measure again tomorrow and make changes
.

No need for change with those results. The pH will rise moderating the CSI. Maintain your FC based on the non SWCG chart in FC/CYA Levels. When you are able to start the SWCG in the spring, then follow that chart.
