Testimonial Center-Vortex Filter from Michael Geier, MG-Zoo

„You asked for a testimonial. I can do that – I've been working with your filters for a long time.“
Regarding my experience: I am Michael Geier from MG-Zoo in Geislingen and have been building ponds all over Southern Germany since 2002 – from small garden ponds to swimming ponds and large koi ponds. I've already completed dozens, and when it comes to filter technology, I've relied on your Center Vortex series for many years. Why your filters? Several reasons. The UP-Flow system is one of them – dirty water flows from bottom to top, and the dirt collects directly at the outlet valve. Other filters work according to the Down-Flow principle, where the dirt collects at the top or from the outside (depending on the model). But that's just one point among many.

What I particularly like
The selective purification is brilliantMy customers can specifically clean only the chambers.,
which need it. The vortex is flushed, but the biological areas with the important
The bacteria remain undisturbed. This saves water and preserves the biology.
Flexible assemblyDepending on the customer, I equip the modular chambers differently.
Those who have many trees around the pond get more mechanical filtration. Koi enthusiasts
get reinforced bio-levels. This makes every system a unique piece.
Compact designThe central vortex with the surrounding chambers – maximum performance
in the smallest space. The right sizing is important: Who your recommended flow rates
maintains, optimal separation is achieved in the cyclone.
The GRP materialStable, weather-resistant, and repairable if needed. My customers invest
not for a few years, but for decades.
The five measuresThere's something for every pond. From the 10,000-litre garden pond to the 20,000-litre
Koi pond to 100,000-litre swimming pond. Makes choosing easy.
Practical tips
Use ball valves, not slide valves. They become leaky over time and need to be replaced.
It will be. I don't have that problem with ball valves.

and the pond will still be properly circulated. The circulation rate is important, so that the
Dirt in the pond moves and sooner or later gets to the filter.

Customer experiences
Filters run for a long time without problems. Even if they aren't cleaned for weeks.
Important to know: Long standing times are normal. The biology needs to be able to work – even
when the chamber looks dirty. Only then do bacteria build up dirt and nitrogen.
correctly. Many people clean too often, thereby disturbing biological processes.
With the correct dimensions, the maintenance required is minimal.
Conclusion
After over 20 years of pond building: a filter must work, be easy to maintain, and last.
The Center-Vortex It does that. That's why I use it.
As far as my experience goes.
