Shouldn't be two hard to clean up, if your filter is working OK. Do you know how to backwash? If not, you'll need to get someone to show you. If your filter IS working, you should see the pressure shown on the gauge increase as it catches algae. And, the backwash water should be FILTHY.
Other than that, forget about all your test results, except two: free chlorine and pH.
To take care of your chlorine, add 2 gallons of 6% bleach every PM, and test chlorine every AM. Once you have an AM free chlorine greater than 10 ppm, stop till it drops below 5, and then dose with 2 gallons again. If your algae is getting under control, you should have more than 10 ppm in the AM before the sun really hits it. Keep letting it drop, and then re-dosing, till you can add 2 gallons and see 10+ ppm in the AM
Meanwhile add a box of borax tonight. Check the pH in the AM -- but remember that your pH reading will not be reliable when chlorine is above 10 ppm. Try to get your pH to 7.6 - 8.0 -- you'll need to drop it a bit later on, but not now.
And, while all this chemical treatment is going on, keep brushing periodically, and vacuuming as you can. Clean the filter as needed.
Once the water is clear, blue, and algae free, repost and we can look at your other readings.
If your water becomes blue and algae free, you may want to carefully check your filter to make sure it's working properly.
