the Bioforce 5500 is a great little pressurised filter. Even though there has been a lot of competition in recent years in the pressurised filter market, the Bioforce name still holds up extremely well. There is not the same self cleaning gimmics, knobs, and gizmos, but the fundamentals of this filter are very efficient. Without all the other complications, the Bioforce simply concentrates on doing the job correctly. It uses a combination of filter sponges, and a bio media called Kaldness. The Bioforce 5500 is only really suitable for small goldfish ponds, I would never advise using any pressurised filter to filter a koi pond. Although they rate the filter at being capable of filtering 5500 litres, I would say 2500 litres maximum would be a sensible volume on this filter. please be prepared to clean this filter every week at least in the warmer months, this will ensure a good through flow, and efficient and stable filtration.
Bioforce is a pressurised system that means a smaller, less obtrusive container size is needed and it can be buried next to the pond out of sight. Pressure also means that filtered water can travel up to the top of a waterfall without the need to be placed at the same high level. New biological filtration from Kaldness K3 bio media. Kaldnes is scientifically proven and in widespread use in industrial water purification processes. As a result, it has vastly superior biological capacity compared to other biomedia used in pond filtration.
