Filter Design 101 Question
Thanks to all of you who post pictures - you've helped me immensely already.
I'm trying to design a little veggie filter for my little pond. It seems to me that I will need to pump the water into the bottom then have it flow from a fitting near the top in order to get it to filter through the media. Is that right? I've looked at several sets of plans but they all look to me like they have the water coming in the top and flowing out the bottom. It seems like that would make it hard to keep the tub filled with an amount of water suitable for the plants. A |

A My veggie filter fills from one end then the water flows though the plants and out the other end. I thought this was standard for veggie filters. -- Bonnie NJ http://home.earthlink.net/~maebe43/ |

news Thanks to all of you who post pictures - you've helped me immensely already. I'm trying to design a little veggie filter for my little pond. It seems to me that I will need to pump the water into the bottom then have it flow from a fitting near the top in order to get it to filter through the media. Is that right? I've looked at several sets of plans but they all look to me like they have the water coming in the top and flowing out the bottom. It seems like that would make it hard to keep the tub filled with an amount of water suitable for the plants. I think I can safely say, I have the simplest VF on the group. I built a second pond, that is only 8-14 inches deep. The water is fed into the VF at one end by a pipe attached to the bottom drain in the pond, so my VF is gravity fed. My pump sits at the far end of the VF and pumps the water back to the pond. No large matter stuff gets to my pump because the Veggies grab them as they go by. One pipe in...one out...water level auto-maintained by gravity (tm). BV. |

Disclaimer: I am entirely mechanically impaired, and am surprised that I am actually even going to attempt this. OK? Now - My pond is only a little bigger than yours. About 3' round, by 3' deep max. I have 2 levels of plant shelves dug around the interior, so the 3' depth is really not accurate. I only dug the middle that deep so that my fish (who don't live there yet) can sink down when the raccoons come. I read that here . Is your filter actually in the pond, with the intake from the pump extended to the drain? Interesting - I hadn't thought of moving the pump. I kind of like that, but I'll have to think about it - I'm not sure that will work for me, only because my pond gets a of tree stuff in it, and I can't picture how I would be able to insure that the supply line would be kept free of leaves. FWIW, I am trying to do an exterior filter which can double as a shallow pool for my birds to drink from and bathe in. If I can pump water in to the bottom, then I'll be a happy camper. When I think about running the water from end to end, I have a picture of water either running over the top of my holding tank or not reaching the top in a manner sufficient to keep the plants healthy. Of course, that was before I saw the pictures of the stand pipe. A |

Of course, that was before I saw the pictures of the stand pipe. My main pond is nearly 2500 gallons or so...rough estimate. My VF is about 500 or so, or at least it will be when I am done with it. I need to redig a few areas. I tossed together a quick diagram and posted it, http://www.darofamily.com/jeff/links...pond_diag.gif. My apologies for the kindergarten look...I am at work and have only MS Paint to work with, so the graphic is lame. I think it explains my setup though. I went with this plan because I wanted a bottom drain. I don't want to have to clean a 4' deep pond every year. I am hoping the muck gets pulled into the VF. I don't mind cleaning that out. Right now I am getting a lot of sediment in the VF. I have no idea how the main pond is because I have a clay problem that prevents me from seeing more then a foot down. Hope this helps. BV. |

BV, is the pump in the VF higher than the intake in that pond? (Your VF is 8-14" deep - is the filter at the deep or shallow end?) Inquiring minds! ;-) -- zookeeper |

Inquiring minds! ;-) Currently my VF does not have a shallow end or deep. It is just a mottled mass of different depths. I had hoped the differing depths would cause fall out, but I won't know until I drain it this weekend. I plan to dig a few areas deeper. Right now the fill line, and the pump sit in nearly the same depth, although the pump might be slightly lower, not sure. The key thing, is that the VF is gravity fed because the feed line is below the surface level of the main pond. So my VF always has water. BV. |
