Changing Bio Filter
Here is another question I need your help on.
I started my pond with a Laguna 4500 Powerflo Filter. After day 1 realized this had very little mechanical filtering, so I took a 20 gal plastic storage box, cut a 2" hole near the top, stuffed a foam mattress egg crate in it and set it on my pond ledge (no lid). There is still a path of least resistance where the water doesn't have to go through the foam and potentially spill over the sides instead of the outflow hole. The Laguna outflow empties into the box. The box does catch significantly more than the Laguna whose inflow is directly from the submerged pump. Between the two they seem to work well, bio and mechan. I want to eventually augment or replace some of this with an upflow filter. In the mean time the foam filter is very unsightly, and slowly collapsing the built up ledge it is sitting on. In the short run I am considering a smaller change- take a similar box, move the water and foam into it (uncleaned); and plumb it with some pvc outflow pipes so it does have to sit on the ledge causing damage and looking ugly. My biggest question is will I lose a lot of biofiltering in moving the contents (short term). It is working and if advisable I could wait untill I got the upflow filter built and cycled. I was also wondering if it would be detrimental to plumb the Laguna filter directly into the box and put a lid with vent holes on the box (for appearance). Right now it just falls from two outflow pipes into the box with no lid. I wonder how much I would be downgrading the biofiltering of the box by cutting down on the splashing into the box and cutting down on the available air to the box, since it is currently uncovered. Again I am just looking for educated guesses. Thanxx Bill Brister |

Changing Bio Filter
Bill, you must have scared us off with the request for "educated" guesses.
;o) Maybe we need a picture?... though I do believe to-leave-as-is till 2nd filter option is up and running for a bit, is a good idea. ~ jan On 11 Apr 2004 21:38:12 -0700, (NewbieBill) wrote: Here is another question I need your help on.
