SKIPPY FILTER QUESTION
Hey,
Does anyone know if it is normar to find a skim layer of "black sludge" at bottom of tank and directly on top of all filter media at end of season with a Skippy Filter. I found approximately a 1/4 inch of sludge which did not totaly "stink" but did have a slight hint of decomposition by anaerobic bacteria. This was the first season I experimented with the Skippy Filter on my "NEW" 700 gal. pond. Next year the pond will empty into a larger 4000 gal. pond with a vortex filter. The small pond will actually become a vegy filter. |

Some (most?) of your filter media was being bypassed by the flowing water. Those areas would become anaerobic and smelly. -- Carol McKoi.... frugal ponding since 1995...

bottom of tank and directly on top of all filter media at end of season with a Skippy Filter. I found approximately a 1/4 inch of sludge which did not totaly "stink" but did have a slight hint of decomposition by anaerobic bacteria. This is normal for a bio- filter, my bio filter does the same thing all year long and I back flush it as needed ( once or twice mid season) - the sludge is a bi product of the bacteria process in the filter. In the fall, I wash the media out as well as possible and hang it up to dry before I store it for the winter - ready for next spring Gale :~) |

This was the first season I experimented with the Skippy Filter on my "NEW" 700 gal. pond. Next year the pond will empty into a larger 4000 gal. pond with a vortex filter. The small pond will actually become a vegy filter. I've been using a Skippy style filter this year as well. On their website it does mention that you will accumulate a layer of silt at the bottom. According to them this is mineral waste from the breakdown of bio matter. I have this as well, and will just back wash it onto the garden. There is a slight smell to it, but nothing compared to settled fish crap. Like you say, there is also a layer of crud on the top of the media. I expect that this is a thick layer of bacteria with small particles stuck to it. Near the surface oxygen is dissolving into the water, so bacterial growth will be greatest. I've been very pleased with the Skippy filter this year. Previous summers I was cleaning the oase filter every week. This summer I have not cleaned the Skippy filter once. I found that the oxygen levels in the pond were very low when I first installed the new Skippy filter. I think the amount of bacteria must have been vast, there is certainly a lot of media in the filter for it to grow on. Some extra aeration soon fixed it. David |
