If your pool has only been open a couple of weeks and you have only been using a few trichlor tabs, your CYA can't be too high yet. So, I'm going to suggest shocking the pool up to about 15ppm and try and keep it at that level consistently by testing a couple times a day and each time adding enough bleach to get back to that level. Each gallon of bleach in your pool will add about 2ppm of chlorine. Use that as a reference to help you figure out doses of bleach to add when you test.
Your pH needs to come up some more. Go ahead and add some more Borax and try and get it between 7.2-7.8 although I like 7.4-7.6 best. Don't forget that pH test results will be inaccurate when your chlorine levels are high, so test it before you add bleach in the evenings. Your alk is also pretty low. Go ahead and start adding some baking soda to raise it a couple lbs. at a time. You can add baking soda and Borax at the same and they both go into the skimmer slowly while the pump is running.
Once your cloudiness is cleared, you should switch to using some cal-hypo for awhile to add needed calcium. You'll want a CH reading between 200-400.
Order some CYA reagent so you can get a reading as that is an important one to know.
Hope this helps!
