Let's try shocking the pool up to about 12ppm this evening when the sun is off the pool. Then, test it again in the morning within 2 hours of sunrise and let's see how much chlorine you are losing overnight. If you lose more than 1ppm of cl overnight, that will tell us that the algae is not dead. Report back here tomorrow with your results. Run your pump 24/7 and clean the filter as necessary.

Until you can get a good kit like I suggested above (you need one!!) go to Walmart and pick up a cheap OTO/Phenol Red kit. (The one with the yellow and red drops.) That will be better than the strips. The OTO kit will only measure chlorine up to 5, but you can force it to go higher with a dilution method described here: Testing Without a Good Kit

Your TA is good, pH is ok at 7.2 but don't let it drop any lower. If it does, you'll need to bump it up a little with some 20 Mule Team Borax (laundry aisle at Walmart.) In fact, while you are buying the OTO kit, go ahead and pick up a couple boxes of Borax while you're there to have on hand. Your TH is ok but you don't really want it any higher, so no cal-hypo for this pool.

Report back tomorrow with the results of the overnight test.

Hope this helps.
