A little clarity, if you please.

These are referred to as “bio balls”. You can purchase them from ACE hardware on MI for about $0.15 each. I used these in a bio filter I made and they seemed to get the job done by “producing ‘good bacteria’” in the filter environment. The short video below will show the clarity of the pond water. It took about 4~5 weeks before the water cleared. Initially it was quite clear but then with algae and other things happening it became quite opaque. Then suddenly within a 24 hour period the water cleared. I have read where it is best to not change/replace the filter materials until the circulation of water through the filter is sufficiently reduced. Early on I changed the filter weekly and the water never cleared so there must be some truth to this. |
This video demonstrates the effectiveness of the bio filter. The filter is visible later in the video along with the tangle of pad vines and old flowers that sink below the surface after the bloom is finished. The small fountain action is from a solar pump. The water that it pushes is not from the bio filter. I had originally wanted a fountain but in a small tub like this the water was redirected by wind and the tub was almost pumped dry. Also water lillies do not seem to like a lot of agitation. You can compare the water quality to pics posted below this post. Double click the video to restart. Just in case you missed something.  |
