Decided to clean the filter, today. Wasn't looking forward to it...lots of
string algae in the filter and what just looked like muck. I thought it was
going to be a grungy job (I have a modified Skippy filter on this pond,
upflow through filter media, cut up and pressed between two light grates,
covered with 2 inches of gravel, runs year 'round). 'Lo and behold, opened
the drain and backflushed with the hose, everything clear again with little
actual trash to pull out. I was so happy. BTW, I noticed with this pond, (as
Jan mentioned something similar earlier about hers), that although the
filter grew string algae, the pond has remained clear. Couldn't ask for
more, I guess. Great weather in TX this weekend!
