Hi, my name is Dan, Owner and Founder of Clear Concept Aquarium Maintenance of Denver. My experience with fish began as a hobby over 10 years ago. Since then I have used my extensive knowledge in Fresh and Saltwater aquariums to help others maintain and clean their aquariums. Please browse the pictures on this website displaying a handful of aquariums I have maintained over the last several years. My experience in fish, equipment, chemicals, buffers and food will help ensure your fish are healthy and happy.
