CSI Index Fibreglass Pool

[lukeyluke]

Hi everyone

Got our 1 Year old Fibreglass pool running great at the moment, thanks to the wonderful resource this website is!

But I have a question regarding CSI, it's sitting at -0.82

I have confirmed with my fibreglass pool manufacturer that there is no calcium in the gelcoat or filler, so not sure I need to be too concerned but wanted to double check.

Here's my numbers

PH: 7.4
FC: 5
CC: 0-0.5
TA: 80
CH: 150
CYA: 60
TEMP: 25c

Leisure Pools suggest a CH of no more than 120

Would love everyone's feedback

Cheers Luke

Luke, you had a discussion about Ch and CSI in this thread. Follow the recommendations there from @aussieta and let your pH rise to 7.8 and your CSI will come up.

G'day from Sydney Australia and would love your opinion!
