Hi, You are doing the right things to kill the algae and probably have killed it. Now you must filter out the dead algae. Unfortunately the intex pools have weak filters so it may take a long time to clear it. Keep your chlorine level up so as not to allow the algea to return and keep the filter on 24/7. In time it will clear. Depending on how cloudy it is it probably might be ok to swim your choice.
