Sounds like you're making some progress--just keep the pump running and clean the filter as your pressure indicates until all the dead algae is out of the water. And make sure that your chlorine level never drops below 3 ppm so you don't have to fight that battle again! Your TA level is not high enough to cause concern about rusting. Also, it is normal to have a temporary rise in pH when using bleach, since the pH of bleach is 13! However, as the bleach is "used up", the pH goes back down--so don't adjust your pH just to keep up with the bleach.

You don't list a reading for calcium hardness--if your CH level is high, then dropping the TA can have a clearing effect on the water. Also, if you were to lower your TA down to around 80 or so, you might find that your pH is a lot more stable. However, if the TA of your fill water is 220 or higher, then it'll be a constant fight to keep the TA down due to frequent refilling, and since it's not really causing you problems, it really can be left alone for now. Those things would be the determining factor in whether or not I would lower the TA if it were my pool. If you decide to do so, here is the procedure: http://www.poolforum.com/pf2/showthread.php?t=191

Above all: if the kids are going swimming in a cloudy pool, make sure you keep a good eye on the swimmers, especially in the deep end--cloudy water can make it hard to see somebody who is in trouble!!
