Recommended Levels?

Hi,

Is there a FAQ with recommended levels for pools?

I generally follow trouble free pool and would be interested to compare to this site's recommendations.

I would be inclined to go with TFP as there levels would be the same as here, albiet no two pools are identical

The levels can't vary a lot, can they?

I doubt that they vary much between identical pools
I have a covered pool so my CYA is about 20 whereas an outside pool would be 40-50 or if you are using Trichlor/Dichlor would be higher
For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm.
For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm.
For every 10 ppm FC added by Cal-Hypo, it also increases Calcium Hardness (CH) by at least 7 ppm

The higher CYA will need more chlorine to be effective
If you have a waterfall, infinity edge or something that aerates the water your pH will rise so you will have to reduce it
Your fill water will also make a difference high or low calcium, iron
Your pool construction, plaster pools require calcium whereas vinyl and fibreglass don't
Do you get my drift?
