Hello all,
First off I would like to thank you all for putting together quite the collection of knowledge for newbies like me to consume. I have a calcium hardness question that I hope someone can help me answer.
details of Pool
Gallons: 15568 (1k of which is a spa with spillover)
Stonescapes Aqua blue plaster
FC - 4
PH - 7.6
TA - 80
CYA - 55
CH - 430
Temp - 67
CSI - -.06
Tap water has 150 CH
I’m using 7.5% bleach and muriatic acid to Maintain FC and PH. I used Leslie Pools Hardenss Plus to raise CH from 160ppm to 430ppm and I’ve used Baking Soda to manage TA. My pool company does maintain the pool for free the first few months and believe they added cal hypo once in the past 4 weeks. I have since asked them to stop coming to maintain the pool as I will be taking over this responsibility using the TFP method.
The reason I brought CH to ~400 was because this was the ideal midpoint provided in the Pool Math app. I’ve since done some research on this and it seems that this may be too high? I understand it’s manageable and folks have way higher numbers. But why does Pool Math have an Ideal range of 350-550 when it seems that most forums posts on this site consider it too high?
thanks!
John
