The Colorado Aquarium Society, established in 1947, is an open group for aquarists to share their interest in all facets of the aquarium hobby. Our members consist of advanced expert hobbyists as well as beginners and all levels between. If you are interested in learning about the hobby, sharing your experience in the hobby, or would like to discuss any aspect of fish, invertebrates, plants, aquariums, ponds, and amphibians, The Colorado Aquarium Society General Meetings are open to the public and everyone is welcome!
The CAS was established in 1947 and incorporated under Colorado law as a non profit organization on November 6, 1962.

Random Tip #6 - Beginner While using bleach around fish can be a scary proposition for a new aquarist, it is important to know that most bleaches are Chlorine based. Therefore, you can soak ornaments and tanks in a light bleach solution and then use a heavy dose of De-Chlorinator to re-soak them... making them safe for use again. Please note: Scented bleaches may contain additional chemicals and should not be used. - T. Fells Add Your Tip
