I dont know about you guys but I like reading the old fashioned way. On paper instead of on a computer screen. So I am always on the look out for some good referance books on aquariums and any other interests that i have. So if you know of any that would be helpful, let me know about them and so every one else on the boards know of them too. A couple that I have are Natural Reef Aquariums by John Tullock Very informative on setting up different kinds of natural reefs by keeping the species from the same areas in it. And what you can do with the lighting. And also about setting up natural ways of denitrating by using live rock and DSB. The Book of The Marine Aquarium by Nick Dakin Has a list of about 300 species of fish and their care requirements. Also has information on setting up tanks but i found the other book more informative. Brian
