Bio filtering without bio falls ?
I have a 300 gallon pond with no waterfall. I did install a skimmer.
http://www.pondsolutions.com/skimmers.htm The skimmer simply pulls water in through the weir, filters through a 2" thick foam, and then pumps the water back into the opposite end of the pond. As can be expected I still have alot of problems with algae bloom throughout the summer (MN, so only about 6 months). I prefer not to use chemicals any more than necessary, but find myself using Poly-Clear about once a month. Stats: 320 gallon pond, 500 gph pump running at about 400gph, 4 shebunkins (about 4" ea), a fair amount of plan material. Want to add a couple more fish. One thought I had is to bag up some lava and place it around the pump (behind the filter) so that water will get pulled through and hopefully bacteria will work on the algae. 1) Is this likely to work? 2) Any problems with the pump overheating or other potential problems? 3) Better solution? Thanks, |

Bio filtering without bio falls ?
May I assume that you're looking for the cheapest/easiest way to fix this? I
had a lot of problems with the floaty particulate matter in my pond: to clear it up, I made a bag of window screen, which I stuffed with more window screen and several yards of cheap mesh (like bridal veil, but cheaper!) (I learned that trick here on this board . . . thank you very much!!!). I placed this on top of the framed net in the skimmer box. When the algae is heavier, I have to wash it off twice a day; later on, maybe only once every other day. But I live in FL, and have a LOT of algae. The window screen/veiling is easy to clean, just blast it with the hose and put it back in place. It took a week or so, but then the water got very, very clear. I have several "layers" of filtration, so I was able to dispense with the foam in the skimmer box in lieu of the pillow of material for the "fines". In your case, the foam is the major source of your biofiltration, so I would NOT suggest you remove it, just put the pillow on top of it. Bacteria will not work on algae: the bacteria work on the ammonia conversion process, so a bag of lava rock would only clog up with the algae, and is a real pain to clean (heavy, too). Another way to get rid of the algae is to use a UV. If you don't want to use the Poly-Clear, acquire some Koi Clay (calcium bentonite). It's a natural product, will provide a lot of trace minerals for the fish, and acts like a floculant. If you have any questions, let me know. Lee "Folklore" wrote in message ...

Also, good bacteria needs good aeration, since you have no water fall
perhaps a bubbler in the filter would be a good idea? ~ jan On 15 Apr 2003 10:45:15 -0500, "Lee Brouillet" wrote: May I assume that you're looking for the cheapest/easiest way to fix this?

Thanks Lee. So the bridal veil filters better than the foam?
How do you use the Koi Clay? Thanks, Aslan... On 15 Apr 2003 10:45:15 -0500, "Lee Brouillet" Said: May I assume that you're looking for the cheapest/easiest way to fix this?

Bio filtering without bio falls ?
Sorry, I was gone for the weekend!
Leave the existing filter in place: it's where your bio-bugs are living. Put the "pillow" or mesh bag on top of the foam filter. You'll be able to pull out the pillow daily (or twice daily, if needed) to wash it off without disturbing your bio-bugs too much. Koi Clay is calcium bentonite; it's the same stuff the Japanese use in their finishing ponds prior to their big shows. It has lots of trace minerals and helps their skin and coloring (whites/whiter, reds/redder, etc.) The normal useage is 1 Tbs. per 1,000 dissolved in a bucket of water and distributed around the edge of your pond. It will gather all the floaty-stuff and take it to the bottom of your pond, just like the chemical stuff does. You CAN NOT overdose: the worst that can happen is that your pond will appear milky for a few hours. I usually do my pond in the evening, and it's crystal clear by morning. I have a light in my pond: clay makes the water sparkle and the bubbles from the air stone look like crystal at night. A side benefit is that it will also bind nitrItes, so it's a very good thing to have available with a new filter. All in all, it's a very benign additive with remarkable benefits. And no, I don't sell the stuff . . . s Lee "Folklore" wrote in message ... Thanks Lee. So the bridal veil filters better than the foam? How do you use the Koi Clay? Thanks, Aslan...
