The water in my pond has gone all cloudy, now this isnt from the alge its not a green cloudy but a general cloudy, if that makes sence. I tested the water and all are normal except i have hard water. What can i do to get rid of the cloudy water? could it be from the temp of the water, during the day the water temp has been getting up to 90, its been hot here in so cali 100+ for the last 2 weeks.
