Thanks for letting me join! I don't have time to research, big project at work. So, quick questions..... What is used for quarantine on sick fish, and are there good treatments for ich that won't kill every invertebrate and microorganism in the tank. I have a 150 tank that I ran on canister filters for about a year. Just got a refugium that is truly awesome but I need quieter pumps LOL. I have about 15 small fish, misc. crustacea, an urchin and 2 anemonae. The rock is thriving, even the apatasia, the harware stores here are pulling their lye off the shelves because its selling like mad for drug production, DMT users, and meth too maybe. What can I say, it's Albuquerque......
