What happens if cyanuric acid is too high?
When cyanuric acid levels get too high, it can cause something referred to as chlorine lock, which basically means your chlorine has been rendered useless. You’ll know it has happened when your chlorine test shows very or little chlorine even right after you’ve added it to the pool.
Is it safe to swim in a pool with high CYA?
High CYA. Yes, your plan is reasonable. You probably won’t even notice the FC level being that high since the active chlorine level is proportional to the FC/CYA ratio so is roughly equivalent to a pool with only 0.07 ppm FC and no CYA.
Does CYA reduce over time?
CYA does reduce over time and a deep end discussion about it is in this thread, Degradation of Cyanuric Acid (CYA). Thanks. Based on my measurements I lost 20 ppm in 7 months, so about 3 ppm per month, which seems reasonable based on the thread.
How much water can you drain from a cyanuric acid pool?
How much you drain will depend on how high your CYA level is. If it’s just a little high, you can probably get away with just draining a few gallons. It’s not an exact science, but if your CYA level is up 10%, you can start by removing about 10% of the water.
Is it safe to drain pool with high CYA levels?
And yet, we encounter many people that are hesitant to drain—or even dilute—their pool to reduce CYA levels. Perhaps there are valid reasons—costs, structural risks, labor, environmental concerns—for not draining high CYA pool water. That being said, draining and/or diluting water is still the most economical way to lower CYA levels in a pool.
What to do when cyanuric acid is too high?
Also, when CYA is too high, there’s not much you can do to decrease it except to dilute it. And to do this, you’ll need to drain some of the water from the pool and add more, which is time-consuming and wasteful.
Can you put cyanuric acid in a skimmer?
Note: CYA can damage vinyl liners or filters if added directly to them. And some manufacturers actually recommend this. But even if they do, it’s best to add it to the skimmer instead. How to Lower Cyanuric Acid Levels. Just like knowing how to raise the CYA level in your pool, it’s also crucial that you know how to lower it.
Can a pool have too much cyanuric acid?
As long as the cyanuric acid concentration is less than 20 mg/l, there will not be any problem. Once a level of 70 mg/l is exceeded, cyanuric acid becomes problematic. Too high a concentration can, however, easily be solved. All you need to do is add fresh water to the pool (3 to 5% of the total volume).
