Depending on the size of your body of water, fish population and general health of your water prior, you have a few options.
1) Take the advice of the '48 Braves,
“Spahn and Sain and pray for rain”.
2) Nothing. Run your aerator as much
as possible without overheating the
water.
3) For my Amish customers, I use a
large hoop, cheesecloth seine net. It's
tedious and time consuming but it
works, eventually
4) Use an algaecide/chelated copper
compound like, Cutrine or Algae-Pro.
Please note, a sudden die- off of algae
can cause a fish kill. Planktonic algae
have a very high reproductive rate, so
re-bloom may occur in just a few
weeks. Several treatments may
be necessary? No matter, never treat
more than 20% of the water per
treatment and follow all labeling
instructions.
