Waterbear..... yellow is very light and sweeps easily cya is 65 dave
Are you sure it isn't just dirt, dust, some sort of pollen, etc,? Has your chlorine dropped below 5?
just checked it and is 4.0, Hopefully is just pollen trees all around
If your CYA is 65 and your chlorine is 4.0,you are flirting with an algae bloom! Take a look at the Best Guess Chart in my signature below. You gotta keep your chlorine in range or ........ get used to green pools!
