if you go here http://www.suiso.com/v2/index.php there is a link to a pdf document of an ADA beginners manual, you have to register with the site first but it's pretty interesting once you download it, about 7meg.
It's a really good site, I'm a member over there too, I especially love the video of c. japonicaryan_suiso said:Thanks for another link to my site
I see a lot of people are interested in this. This was just a scan I did of a free information pamphlet ADA sent out to certain LFS in Japan that requested it for English speaking customers, like me at the time.
Now that there is one shop selling ADA goods in America:
http://www.aquariumdesigngroup.com
And another one on the way:
http://www.aquaristics.com
I hope to be the independent knowledge base for all things ADA. I know ADA products. I have used some them for close to 9 years now. My wife is Japanese so she helps me with translation when necessary.
I hope both companies succeed in this venture. There is a need of ADA goods in America. If the information on the products is there all shall win!
Sorry, just my cheerleading on ADA.
