Hi Wayner,
For future reference the fish will eat any mosquito larvae that make it into
your pond so you don't have to use any product on them.
As a rule we don't recommend clearing agents in ponds.
Fish will take care of mosquitoes and plants will take care of algae. Cheaper
that way which means more money for plants and pretty fish.
