DH tested the water this evening and our best guess is the chlorine level was about 6 or so. He added about a liter of bleach to the pool tonight. We're pretty sure the algae is dead, and we're just waiting for the pump to be able to clear the water up for us. I'm not really wanting to get back in until I can see the bottom of the pool in the middle. We are considering upgrading to a larger pump/filter set.
I've been writing my thoughts about that in a different forum:
