If I'm not getting a Cyanuric Acid reading with my test, does that mean there is no conditioner in the pool?

A  Answered on 12/20/2012 by InyoPools Product Specialist Patrick P.

Things such as temperature, pH, alkalinity and calcium can cause false readings. Your best gauge for determining whether you have sufficient Cyanuric Acid levels is whether or not your pool is holding proper chlorine levels.

Each year when I open my pool, the chlorine demand is very high. This year I needed 41 lbs of shock. The water is balanced when the pool is closed and is covered the whole off season. I do not have any contaminants entering the pool. Can you give me any ideas?

A  Answered on 10/18/2012 by InyoPools Product Specialist Patrick P.

Without a full water analysis and more information about the swimming pool, it is difficult to diagnose. The swimming pool should be shocked at least once every 7-10 days. You would likely be using 1 bag per 10,000 gallons of pool water. Aside from that I would recommend checking the cyanuric acid level as an imbalance can cause the swimming pool to use more chlorine.

Cyanuric Acid level was marginal

Added 4 Lb. Jar of Stabilizer to my 30,000 gal in-ground gunite pool. This raised my Stabilizer level from 35 ppm to 60 ppm. Now my chlorine level does not burn off as quickly on sunny days with the cover off
