Overdosing on clarifier can cause the water to cloud. bad news is that it can be difficult to get it to clear after that (depends on exactly what clarifier you added, I do not mean brand name, I mean the actual ingredients in the product)
Saying that the chlorine and pH are a little high tell us nothing. We really need the numbers. Also, if your pool is at shock level the pH will read high when it is not. This is a known chemical interference. High sanitizer levels cause the pH to read higher than it really is. IF you have a GOOD test kit (such as a Taylor) then the chlorine can be at 10 to15 ppm before there is interference but with many inexpensive kits and strips this interference starts as low as 3 ppm FC levels.
