Hello,

I was out cleaning the pool today on a beautiful day in Huntington Beach, CA and decided to check more than the Chlorine and pH and the results are confusing. All but my Calcium readings were pretty normal and I don't know why or even how to fix the problem. Is it a problem?

First, I have a rather small pool and spa combination (Gunite, completed in June of 2006). It is probably in the area of 12,000 gallons. The finish is pebble sheen and I use a SWCG in combination with a DelOzone system for sanitation. I have my SWCG set at 25%, and run the pool 4 hours per day. I will increase the SWCG percentage and hours run progressively to summer time.

Results for the pool today:

Chlorine 5 (I need to lower my SWCG percentage)
CC 0
Free Chlorine 5

pH - High, right at 8.2 (added acid)

Alk - 100

Calcium - OFF THE CHARTS!!!! The chart with my kit suggests that 200 - 400ppm is ideal for a pool, but I would guess that I am over 600.

CYA - 80ppm

I have concrete coping, natural stone tile and extensive use of boquet canyon stone and there appears to be no problems with calcium build up or any type of problem with my pool. Other than cleaning and adding basis on a weekly to bi-weekly basis, there has been absolutely no problems with my pool, rock work or tile. Do I have a problem, if none is obviously presenting itself to me. I just want to stay ahead of the curve and try to prevent a problem before it happens.

Please advise and thank you in advance for your input!

Regards,

Mike
