pool got cloudy after adding pH UP

[Watermom]

DE (diatomaceous earth)is a white powder that is the filter media for a DE filter. It is actually the ground up fossilized remains of tiny aquatic organisms called diatoms. You can buy it at a pool store. Just buy a very small bag and don't let them talk you into buying a bunch of other stuff while you are there! They'll probably try!

not a stupid question; there's a lot to learn about pools:
