Most of us struggle for every centimeter on the shelf to place another tank. Harald Khaden took a different approach – he built 8,000 liters right in his house. How does one plan such a colossus, what must the floor support, and how does technology work in such a volume? Join us for a unique online lecture that will take place with Czech subtitles thanks to Zoom technology.
Do you have a "hundred" at home and think it's small? Or are you planning your life project and looking for inspiration where space and creativity are not limited? We have a tip for an event that will take your breath away.
The international group Cichliden-Forum invites all aquarists to an exclusive online lecture Harald Khaden, who will guide us through the construction of his gigantic 8,000-liter biotope aquarium.
What can you look forward to?
Harald is not just a theorist, but primarily a builder. During the evening, he will show us:
- The complete process: From initial planning and statics to filling.
- Know-how: What to watch out for to avoid disasters with such large volumes.
- Visual experience: The lecture is full of high-resolution photographs and videos that will transport you directly to the aquarium.
- Technical details: Filtration, maintenance, and specifics of fish breeding in such a massive system.
Without language barriers: Czech subtitles provided!
The organizers are thinking of us too. The lecture will be conducted in German, but thanks to automatic translation of subtitles in real-time directly in the Zoom application, even those who do not speak German will enjoy it. Our German colleagues send a message: “Of course, we warmly invite our Czech aquarists to this interesting lecture!”
