Duke... here's what I would suggest. First, get a new ammonia test. Re-test your RO and your tank water with the new test and take action from there. Secondly, go look at other people's tanks and see how they have them set up. Ask questions, learn what people are doing and why and plan your setup accordingly. I'm getting ready to tear down my tank and set it up better, adding a sump and making some other big changes. I would welcome the help and you could probably learn quite a bit by seeing the equipment and how it works together. Let me know if you're interested and I'll let you know when I'm doing it. Third, start reading everything you can find, one topic at a time here on MR, and on sites like Melev's, and get yourself a good book or 10. Don't give up... it's tough but worth it.
