Luc & Anja,
I totally understand what you mean by needing a break from the hobby. I did the same about 4 years ago, I sold everything even equipment.
Now you can go on holiday for 3 weeks and have no worries at all!
I will make a prediction here, you will have another tank set up within 24 months. I hope I'm right as you're one of the pioneers of our hobby.
When you do set back up you are welcome to take some more frags.
If you're ever back in the UK feel free to pop in.
Best wishes,
Tony
