Slow sand water filtration (biological sand water filters) after 8 years.

This is "filter_guy". I checked in 8 years ago in 2013. Could not retrieve password. Start over. All the slow sand filters are still working on the original ponds. From back then 8 years ago. They run 24/7. Crystal clear water. One new pond with fish. Worked well until we had a disastrous cold spell here with snow, and ice. That pond/filter is now recovering.
