Cloudiness is either 1) poor filtration or 2) developing algae bloom or 3) over-saturation with calcium carbonate. So try taking a bucket of pool water and add some bleach to it (be generous and add several ounces per gallon). If the cloudiness dissipates or falls to the bottom after about 30 minutes, then the cloudiness is from algae and you need to keep the chlorine level higher in your pool (at least 20 ppm if not higher) for a longer period of time. When chlorine levels drop in a pool, in particular overnight, then the chlorine is getting consumed most likely fighting algae. See if you can measure the chlorine level after the sun goes down and then again early the next morning and let us know how much it drops (and what it started at).
If the bucket test doesn't have the water clear up, then take a fresh bucket of pool water and add some acid to the bucket to lower the pH. If the cloudiness goes away, then the problem is an over-saturation of calcium carbonate. I don't see where you ever measured your Calcium Hardness (CH) level -- perhaps it is very high, but it would have to be really high, like 1000 ppm or more, with your other numbers to show cloudiness. Lowering the pH some will help, but lowering the CH would be needed as well through dilution with lower CH water (you can test the CH of your fill water as well).
If the above two bucket tests don't clear the cloudiness, then check your filter to see if it is clean and be sure you are filtering frequently enough -- at least one turnover per day, possibly more. If you have an above-ground pool without a floor drain, then if the cloudiness seems to be more near the bottom of the pool then the circulation is poor and you can use a flocculant to clear things up faster -- OMNI Liquid Floc Plus.
The one other possibility is, gulp, high phosphates. I say "gulp" because we haven't sorted out what really goes on with them -- we know that up to around 3000 ppm or so that they are no problem, but some people swear that at high levels that chlorine gets rapidly consumed and that the pool gets a strange persistent cloudiness, so getting the phosphate level tested is something else to try. If it's high, then there are expensive phosphate removers that can be used.
