Does Chlor Brite have cyanuric acid?
In this regard, does pool shock contain cyanuric acid?
Cal hypo is the most powerful type of pool shock, making it great for super-chlorination. This will help you quickly return to the water. Calcium hypochlorite does not contain any cyanuric acid (CYA), therefore it will not raise the CYA level in your pool. This pool shock is very effective at killing algae.
In this way, how do I lower the cyanuric acid in my pool?
If the CYA levels that are more than just a little high, diluting your pool water is the only way to lower them. Allow splashout to bring down your water level, then top off your pool with fresh water. If the levels are extremely high, you may need to drain your pool and refill it with fresh water.
Di-chlor contains stabilizer which will increase the cyanuric acid level in the swimming pool. It can be used as a shock treatment (1 lb per 10,000 gallons) or as a maintenance chlorine (3 oz. Di-chlor should be added in the evening and swimming can be resumed once the chlorine has returned to normal levels.
