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.

My chlorine always seems to be low no matter when I test it. What can cause this?

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

I would recommend checking the Cyanuric acid levels and adjusting if necessary. Cyanuric acid (conditioner) protects the chlorine from being burnt out by the sun.

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.

the cyanuric acid level is always reading very high in my pool. What are the consequences of a high reading?

A  Answered on 7/3/2016 by InyoPools Product Specialist Alex V.

Joseph, The first issue would be the efficacy (effectiveness) of the chlorine to act as a disinfectant.  Higher levels will bind with the chlorine, making it slower acting to kill bacteria and micro-organisms, and prevent algae.  Higher levels will also increase cloudiness in the pool water. At this point, it would be recommended that a portion of the pool water be replaced with fresh water, as there are no other means of reducing the cyanuric acid in pool water.

how do u reduce cyanuric acid in pool water

A  Answered on 8/21/2017 by InyoPools Product Specialist Lennox H.

Hi. Howard. The most effective way to reduce the Cyanuric Acid in a pool is to partially drain it. They are some products that can reduce the CYA in a pool but unsure of their effectiveness.

My pool’s stabilizer level was low.

Written on 4/23/2024 by Guest

Given the much higher price of stabilizer at the local pool store, I decided to purchase some stabilizer at INYOPOOLS.com. I added a pound of stabilizer slowly into my skimmer at a rate of one pound an hour for a total of four pounds. My stabilizer is now at the acceptable level.

Were these instructions helpful?
