Hello everyone this is my first post

My pond is a little over 2 years old now and I can not keep the water
clear this year.

I live in a very hot climate 100+ all summer, the pond is in direct sun
until my trees get bigger.

1200 gallons with 12 ft of water fall length, Pond master 4800 gph pump
with a Pond master pressurized bio filter with a 20 or 22 watt UV light.
the water has always been crystal clear until this summer

HELP Please
