after the polyester batting took a big chunk out of the algae I put regular
filter material in, reticulated foam, screening, etc. and I can now see the
pea gravel on the bottom of the pond. it is amazing how well that bucket
filter works. the ammonia is also back to zero. and I unplugged the heater
and removed plastic off 1/2 the pond and the temp went from 68 down to 52...
yikes. maybe they quit spawning when the temps dropped? the heaters are
back on, the pond is covered for another little while. guess I will have to
wait a bit longer for summer. Ingrid
