The owners have asked me what they should do to clear the algae since
this
is used for recreational swimming and SCUBA diving.

Throw about 8 bales of straw , still tied in a bale, into the
pond...put a couple around the edges so they are half submerged.

Tie a swimmer to one and you will find the facility is used less
subsequently.
