I am new to all this and I have been reading up. I have had my pool for 3 weeks. It got really murky and cloudy. I have added bleach and it is looking better. My DH tested the water tonight and he says the FC is between 3-5 and my PH is 8.2. We just hooked up our new sand filter tonight. What should my priority be? Lowering the PH? I had to buy a test kit from wal mart. I will have one arriving in the mail soon. Thanks for any advice.
