Quit adding all those things that the pool store is selling you. It is not helping.
Have you been using cal-hypo which is often sold as bags of shock? If so, don't add any more as your calcium hardness level is getting pretty high. You also don't want to use trichlor tabs or dichlor shock powder. They both have CYA (stabilizer) in them and your CYA level is already plenty high. I'd suggest just sticking with bleach or liquid chlorine.
Since your pool is cloudy, I'd suggest shocking your pool. (Don't use your SWCG to shock your pool as it will just shorten the cell life. Just turn it off for now.) Shock level is based on CYA levels. (See the Best Guess Chlorine Chart in my signature below.) With a CYA of 60, your shock level is 20. In an 8800 gallon pool, each gallon (4 quarts) of plain, unscented 6% bleach (generic is fine) will add just under 7ppm of chlorine. Each quart will add about 1.7ppm. Use these amounts as a reference to help you to know how much bleach to add each evening. Test your water in the evenings, and each time add enough bleach to get back to around 20ppm.
Sounds like you don't have a test kit. We recommend the Taylor K-2006 or 2006C which you can get through the test kit page in my signature. Do yourself a favor and order one. In the meantime, see if your Walmart has an HTH 6-Way kit to buy. If not, at least pick up an OTO/Phenol Red (yellow and red drops) kit. Either one of these kits will do until you can order the better kit. (It is not available locally and will have to be ordered online.)
Your pH is ok at 7.2 but if it goes any lower, you'll want to bump it up some with some 20 Mule Team Borax (laundry aisle at Walmart). PH readings are inaccurate at high chlorine levels, so test it in the evenings before you add bleach.
Hope this helps. Come back with further questions and tell us when you get a kit and what you get.
