Bottom Drains and Empty Ponds
It is better to pump the water after it passes through the last filter.
Gravity feed all the filters and then pump the clean water back to the ponds. Howard "Dan" wrote in message ... My bottom drain and surface skimmer are gravity fed into the VF and then pumped from the VF into a bio-filter where it then falls back into the main pond. The only problem I have, is my make-shift prefilter on my pump gets clogged and needs to be cleaned about once a week. However, the prefilter is necessary on the pump intake so that the pump doesn't get clogged which is a much bigger job cleaning. Any suggestions for a good pump prefilter?

The pump intake from the settling/veggie pond is above the bottom of the main pond so I never risk emptying the main pond. Over this winter, I had a leak somewhere in my underground plumbing and my water level did drop but when it got below the intake of the pump, the pump just shut off. That never occurred to me. I have been thinking the whole time I would have bottom drain to pump to VF. I guess I could have bottom drain to VF, to pump back to main pond. Does that make sense? Pump FROM the VF to the main pond where the BD is? BV. |
