I had a little algae when brushing the bottom of the pool and cloudy water. The all airy was around 60 so I added alkalinity till it got to 100 then the ph was high so I lowered it and then did a liquid shock 2 gallons at night. This morning the fc is still high at 12 and a little cloudy. Alkalinity and fc are in range . Anything I can do to fix this for a birthday party in a few hours??
