Re: Test results are good but water is cloudy
Sometimes even though there is no combined chlorine you can start to have algae. It is when there is enough chlorine in the water to keep a big bloom at bay. Have you noticed that you have had to add chlorine more often? You will need to take the chlorine level up to shock, and keep it there for a couple of days to make sure all that is started is killed. With a cya of 30, you need to take the chorine up to 15ppms and leave it there being very consistant. Don't let it fall down below 15, and brush and and backwash often, keeping the filter running 24/7 till your water is clear.
