HELP: Koi pond filtration ideas
I've done some searching around and I've found various biological
filtration systems available and I was hoping for some recommendations for a 1000 Gallon pond that WILL have a 1200-1800 GPH pump. It needs to be external and small / and/or buriable. Preferrably one of the all in one that's not heinously expensive. Probably looking at something pressurized and either with a backflush mechanism or cleanable media. (Preferrably backflush, for obvious reasons.) Unfortunately, I don't have a bottom drain, so that's going to screw with the asthetics as the pond is built up about 20" high around the edges in a circle. (If anyone has any bright ideas on hiding all the power / tubing, I'd love to hear that too. ;-) Also looking for recommendations for on-line vendors, etc. I was impressed with what PondPetsUSA.com has to offer, I was hoping to get some more information before I leap off a cliff and buy the wrong thing. Any help you can lend would be greatly appreciated. Thanks, DC |

Lots of us have gone for veggie filters. Have you the room to put one
or more in? Ours on the berm have bottom drains. Easy flush...open a 2" port. You could put a submersible on the bottom of your pond and push the water up a pipe to a berm and falls. You could pretty much hide the pipe by letting algae grow on it. We have no mechanical filtration beyond the roots of many plants. If you could lay a veggie filter alongside your pond, it would look like a grass bed...20" up as well. People have gone to burried barrels...lots of hassle cleaning. I wish I had a really good idea for you. Maybe someone else will.

Buyer beware. Pond filters are notoriously over rated. They will usually
take care of a pond that is half as big as they say, and that is if you don't overstock too much. I would get a filter rated for at least 2000-3000 gallons, if I bought one of the commercial filters. Jim and Phyllis described the veggie filter, and it needs to be at least 10% of the surface area of the pond or larger. Larger is better. Gives slower flow rates, better cleaning, and more room for more plants. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "DC" wrote in message ups.com...

First off, I agree the veggie filter is a good way to go, but hey, if you don't have a barrel system, no put downs please. ;o) I clean my pre-filter only 3-4 times/season and it only takes 45 minutes, the bio-chambers I clean once/year (and one of them runs all year around). When I took it apart just a few days ago, it really didn't appear to need cleaning, but we did it anyway. *My Filter* www.jjspond.us Currently the lids for my system should come next week, I'm excited. Now if money (and space) were no object I'd tell the OP to look into a Vortex filters, imo. ~ jan ~Power to the Porg, Flow On!~ |

Hi Jan,
I don't mean to put down your barrels. As I remember it, they were out of the ground. DC was talking about in-ground or easily hidden filters. As I see it, buried barrels at ground level would be a lot of hassle to clean! That was my reference. Jim ~ jan JJsPond.us wrote: Lots of us have gone for veggie filters.

Thanks, DC Take a look at my filtration system and see if this is what you are looking for: http://home.insightbb.com/~jryates/filter.htm This particular set up is internal, but could easily be converted to an external system. In fact, it is based on an external system I built for my sister a few years back. It is easy to build, and would save you a lot of money. |

Nope, they're buried, only 2" of rim is above ground, takes up 4X4 space, but OP wouldn't need 4 barrels. I'm putting 2 on my 1,000 gallon lily pond (when I can get the guys to move in that directions). As I see it, buried barrels at ground level would be a lot of hassle to clean! That was my reference. Hmmmm, haven't read my website regarding this? No hassle, I pull the screen door stuff out with a garden claw on a long handle. Toss it on the lawn and spray it down. Drain the water out of the barrel with an extra pump and suck the muck out of the bottom of the barrel with a shop vac. The only thing easier would be to have a vortex, where I could open the bottom drain that would drain the muck out. We poor folk do what we can. ;o) ~ jan ~Power to the Porg, Flow On!~ |

I've run stream/waterfall and spillway bucket combos with vegitation for
years and they always did a great job of controlling all but the worst string algae. They are however prone to some maintenance especially if you don't install bottom drains! Lots of dredging muck etc. Also, water hyacinth works wonderfully but has to be watched carefully. You can go to work one day and come home to find an errant bit of it happily diverting water out of the system lol. Due to back problems I had to do away with my stream and buckets setup and opted for a self contained pressure filter and UV setup rated at 2500 gal on what had now been reduced to about a 1450 gal pond. No dice. Pure pea soup all this season, had to clean the thing at least weekly (should/could have been daily). Gave up on prefab, built the skippy using a 100 gal rubbermaid stock tank. Didn't use the floor scrubbies ( no easy way to purchase the stuff from them, I don't have the patience to do checks in the mail lol) but did use tried and true washable 2" thick white matt media from Aquatic ecosystems (approx 30 sq ft) and hooked it to the same 2000 gal/hr pump I'd been using. Still have the 18w UV inline for now as well. In one week has gone from solid green to gin clear. In all honesty I already knew the prefab wouldn't cut it but I had to prove it to myself. If you add plants on top tho do be aware that the roots can infiltrate your media. It aint always fun or easy cleaning them out of there! All in all if you can make 15 sq ft of space, build a 100 gal skippy and make a nice falls around it, or a cedar box for that matter, heck you can hide it many ways and pipe the water back! Mine still looks very utilitarian but the water's the thing for me anyway lol. Total cost was about $170 for me which is much less than the crappy overrated prefab it replaced! One note, I did add a T with a stand pipe on the input to break syphon in the event of power failure or when you just need to shut off the pump. This not only prevents the filter contents from returning to the pond, it adds air to the water column! joe ( who used to be here alot long long ago.... lol ) "Richard Holub" wrote in message ...

I stand corrected. Your barrels are under the ground. The screen makes
good sense. You seem to have streamlined the de-mucking process well, too. I guess I still prefer the open-the-drain method of cleaning out the muck. We just open the drain by turning a handle and watch the junk exit. In the WH ponds, I have to pull out the dead WH after the water has left. Once in a while, I have to pull it away from the drain as the pond empties. I generally flush them with a hose to get the last stuff out. Phyllis laughs when I do...so little left and soon to be replaced by new muck.

First off, G, there is a problem with your website. Try viewing it
from something other than your server (or develpment machine) and you'll discover that there is a javascript call to a page that points to 127.0.0.1 which is the internal loopback address of a PC. (So no matter who visits it, it tries to look up pages on THEIR machine instead of yours.) Offending code: "script language='javascript' src='http://127.0.0.1:1025/js.cgi?pcaw&r=9514'/script" Cheers, DC |

The main reason I'm not considering a Veggie filter is that I simply
don't have the room. I'll have to post a link to a couple of pictures of the pond and related destru... construction. I have serious questions about whether I'll even have room for the 70Gal Skippy (thanks for that recommendation RH and for BestNest... good site I hadn't found). This is why I've been leaning towards something along the Aqua Ultima II 1000 or 2000 (a little pricey but a great formfactor) or the Cal Pump Torpedo Plus 2000 (probably more maintenance, but need to get some user feedback.) The other factor that I haven't mentioned previously is time. I've got about 2 weeks. (Part of a larger, interdependent plan.) |

If you use black ABS pipe, it will hardly be noticeable. I use the white PVC and it is covered with algae and not too offensive. This feeds bio and veggie filters. You might be surprised and how efficient even a small veggie or bio filter can be especially if you do not overload the eco system with too many fish. What I have found is the more simple the set up, the better it seems to work. Maintenance on my system is limited to fall cleaning just before shut down and 'dusting off' before spring start up. The plants will take care of a LOT of filtration for you. Give it some more thought. Success to you! W. Dale |

I guess I still prefer the open-the-drain method of cleaning out the
muck. Absolutely! If one can plumb it, that is a far, far better way to go. My sister, who just put in a series of ponds (11,000 gallons her estimate) thought she was going to use my filter configuration. I said no way, when you've got the dough to go absolute low maintenance, spend it. None of us is getting any younger. I took her out to a similar pond set up like she wanted to do and the ponder demonstrated cleaning the vortex pre-filter. Yuppers, they were sold. I'm heading down there (UT from WA) week from Monday, and I am "EXCITED" to say the least. ~ jan ~Power to the Porg, Flow On!~ |

Do you have a 2' X 4' area, and be able to dig down 2-3 feet, rims need to be a tad higher that the highest level of the pond? Do the words "bulkhead fittings" scare you? If you get all the parts together the filter can be made in a few hours. Connecting it up, which you have to do with any filtration system, probably more time. Silicone everything and 24-48 hours cure time. 2 weeks? Plenty of time if you get all the parts order before hand. ~ jan ~Power to the Porg, Flow On!~ |
