We just spent the spring overhauling our existing pond and adding on.
Previously, we had one pond ~3500 gallons with an accompany bog. We had a submersible pump in the pond, we pumped water up through the bog with a gravity/waterfall feed back into the pond. This pond was just under 2 years old. Never had a problem with water quality/clarity, but had a problem with the bog and the pump. We had river rock of varying sizes covering the pvc under the bog, and the lilies planted in the bog combined with the gunk coming from the pond eventually clogged the holes in the pvc and burned out a few pumps. We tore out all the rock in the bog, cleaned everything out and just lined the edges this time, and put plants in baskets as a trial for this summer. (Downside - removed all biological history we had going!)
So then we added 2 ponds and a stream. The new top pond flows into the second new pond, which goes down a waterfall and into a short 8' stream that flows into the original pond. Bottom drain on the original pond now goes into a 100gal settlement chamber (round sump chamber, gravity feed through two inlets, one near the bottom and one close to the top/pond level), which feeds into a second identical pump chamber for the submersible pump. Right now there is nothing in the pump chamber other than the pump and water. The pump pushes the water back up to the top pond.
My problem is with mechanical filtration. Right now I just have a roll of quilt batting in the bottom to try to help combat the huge pollen issue I'm having.
The outlet is a shower drain about 2/3 of the way up. If I leave the grate on I am currently cleaning it twice a day because it keeps getting clogged and I run the danger of a dry pump. If I don't put the grate on, the pump eventually gets all clogged itself because of the larger bits going into the pump chamber (mostly algae.)
I am flushing the settlement chamber daily through a bottom drain. I need advice on two things:
1) Is there some sort of screen I can use as part of the outlet? I can't find anything that fits, or would stay there easily.
2) Filter media - I know, the age old question. I've been looking at matala mats, matala rolls and sponges in a laundry bag. But with two inlets, it seems I need to "block" both of them so there is not direct flow right into the outlet (particularly from the top one.) So, I need to block/catch the big stuff AND let enough water through.
Taking away all my bio filtration from the bog is not helping as the whole system is now establishing itself! So far water quality is fair in the top pond, great in the second pond and not so great in the original pond.
The ultimate goal would be to be able to go on a weeks vacation and not have the pump run dry because of a blockage!
Any advice would be appreciated! Thanks!
