It is now November 9 in 2022. All but one of the filters are functional. We are now able to start working on the filters again, as we have fully recovered from the back injury. We may be able to have some professional testing done now that Covid has ceased to be a problem here.
There were fires in the Pacific Northwest this year. Very, very bad smoke here for about a month. The smoke was so bad we could not do much work outside. The fish pond filter is cleaning the water perfectly crystal clear. There are still 4 fish in the pond.
