Effective biological filtration is fundamental to producing clear healthy water however not all biological filters are effective!
They need to be paired with a mechanical filter which will remove solids before the biological filter.
Without effective mechanical filtration the biological filters clog up and cease to function – in fact they can become a hazard to pond health.
In the Aquascape System the Mechanical filtration is performed by a surface skimmer which traps both suspended and floating solids. The floating solids e.g leaves and anything else the wind blows in are trapped in an easily emptied skimmer basket.
Our pumps sit in the bottom of the skimmer so in addition to being out of sight they immediately deliver the filtered water to the biological filter.
The Biological Filtration is provided by the Aquascape Bio-Falls biological filter which in addition to starting the waterfall/stream return to the pond contains both foam filtration and a special media called bio-balls which serves as home to colonies of beneficial bacteria which digest dissolved wastes from the mechanically filtered water.
This is what we call a paired system; sizes and flows are calculated, then balanced to try to position the Skimmer and Bio-Falls as far apart as possible for maximum flow.
Keeping a healthy fish population
In a healthy eco-system pond it’s difficult to stop your fish breeding and as much as we love when this happens we want to avoid over stocking.
There are no hard and fast rules but generally if you have more than 1 inch of fish for every 100 gallons then pay attention to the water quality and start thinking if you can re-home some of your fish.
One of the joys of having pond fish is interacting with them at feeding time. Many koi will even stick their heads out the water in their eagerness to be hand fed.
However this can be problematic to water quality – try not to over feed and not more than can be consumed in 2-3 minutes. Uneaten food will decay.
