Oh dear. You need to go to Aqadvisor and put in all of your information: size of tank, filtration, all contents. You will see warnings about your combinations, filtration, etc. Show this to your wife. I know you want a beautiful healthy tank, Kevin, but it is going to be impossible with what you have. You are trying to do what is best for your fish, it is obvious, but this isn't going to work. Here is a direct link to the site. For a very experienced aquarist, they can bend the rules some, but for someone just starting out and still cycling their tank, you really need to follow this advice.
