I have followed this guy for sometime now and find his videos and teachings to be among the best out there, he has now launched a web site which in my opinion is second to none and will serve every planted tank hobbyist well.

Thanks Charlie
I really enjoyed his videos and website as well. Quite inspirational.
He has the perfect mix of science, art form, practical skills, and communication.
