Thanks leebca,
I do understand that the slower you do everything in a marine aquarium the better, but after looking at my empty tank for a month I could not stop myself. I did however use half of the water from a tank that has been set up for more than a year already, and the rest was RO/DI. Maybe I should have my RO/DI water tested a local aquarium store. I didn't notice any problems in my other tank, where I also used the same RO/DI water, but the water changes there were much smaller since it is a year old 40 gal tank. I also cured all the live rock that I added, and mixed it with live rock from my old tank. I'll try doing a big water change and see what happens next. Thanks again for all your advice.
