PondFlitration Filter Questions
I have a PL 4800 with the 3 'media' bags and UV light. We have not done
anything with this filter since we inherited it (we moved into this house with the waterfall/pond already here). Last summer was our first summer with the pond, we rinsed the media bags and put them back in. The pond was reasonably clear, you could see the bottom but it was a little green and hazy. Thought that was normal. Did the same with the filter this year, was the same green, hazy clearness for a little while than the pond mucked up in part due to a leak with the waterfall. We had to shut down the pump to fix the waterfall so I bought a PondMaster filter/pump to keep the water moving while the waterfall was off. To my amazement the water was extremely clear and NOT green or hazy after a few hours of the new pump/filter operations. Long story short, waterfall fixed, no leak back running thru' the pl 4800 water is green, hazy, murky can't even see the bottom. SO, now that leads me to my questions. How long do the media bags last? We are fairly sure these are the original bags, we ran the filter last season for 4 months and this season for 2. During the winter we shut the waterfall down and will be using the pondmaster filter. Obviously, the media bags need to be changed out just need to know how long they last with summer use only. Once we have replaced the media bags how long before the water will clear up? Also our filter has a UV light, we don't even use it the bulb is no good. Is a UV light necessary for the proper filtration of the pond?OR vital to the filters operation? Do they really work? I have read some conflicting reports. I know it is for algae but we used barley straw last year and didn't have any string algae just the little growth on the rocks which the fish eat off of. We used the Barley this year too still no string algae but do have green water. Appreciate some input on this, THANKS! |
