gf im with you and your passion.
Its all about creating a piece of art, but to create the art work you need the best paint brushes possible( The ADA equipment).
The picture you have posted is a true representation of the "The Nature Aquarium" and is what gets me excited about having an aquarium, its what i want in my home.
Its a shame that it seems to be taking a long time for the UK to get the products and hard wear to the same standard as ADA's.
There are places here that sell selective ADA products, but IMO the most important piece of equipment that is true ADA is the tank, you just cant get tanks like that, seamless and ultra clear.
If we could get glass tanks like ADA's then we would be half way there.
If i feel im having a bad day with my hobby i just pick "The Nature Aquarium" books and im all there, reminded of what it is im trying to achieve, a piece of art!
I want to see more glass wear, the inlet/outlet pipes for all tank sizes, i don't want to see ugly plastic green or blue pipes, give me glass any day of the week its all about being discrete.
