The tank is now 15 months old and you can see the changes in that time by looking at the links AcroSteve posted (thanks!). There is lots of startup info in there too.
I just started using ozone and I'm really pleased with the results. I had used ozone in some of my first reef tanks and discontinued it thinking it wasn't doing much. Now I have a truley mixed tank with lots of softies, anemones and sps. I use carbon 24/7, but thought the ozone might get some organics the carbon missed. From the expansion of all the animals, especially polyp expansion of the sps, I can see that ozone is a definate plus for my tank.
