OK, I am reading this book, "Saltwater Aquarium for Dummies". But it has me asking a few more questions.

1. It states not to add more than 10lbs of live rock at a time. So was wondering this, Im getting a 145 gallon tank, will have a sump/refuge tank of 75G - 100G. I plan on getting roughly 125lbs - 175lbs of live rock. As well as probably about 2 - 3 inches of live sand. Can I place all the live rock and sand before I add the conditioned/mixed water in? Or do I need to do as stated in the book, only 10lbs at a time? I probably should mention this is a first set up, not adding rock to an established system.

2. The book also stated that it is ok to use TAP water, as long as it has been conditioned and mixed before adding it to the tank. I know you can do this and be safe if using a RO/DI unit, but is it safe with out one a RO/DI unit?

3. And last question for now, does anyone know a place to get several 5 gallon buckets that are food safe, or should I just call and bug several restaurants in the area?
