Adding DI to RO?

Sounds like you're just starting out with a saltwater tank. Welcome to the forum by the way. If you are new to saltwater, take your time and do plenty of research. It's going to be a while before the system is ready for any livestock. If there's nothing in your system at this time, then there should be no problem using just the RO water for the time being. It will be fine sitting in the tank indefinitely. Just ensure the tank is good and clean, free of contaminants. You might want to provide a little circulation with a powerhead, especially if you're adding the salt mix.

Yes I am new to saltwater and have been reading up alot on things...and I still have a ton more to learn. I am in the process of filling it with RO water. I will then add salt and check all parameters. Next will be adding liverock and cycling it for about a month. I will then add corals, lps, snails/shrimp..etc that dont need too much attention and wait another month to add fish. This is because I will be gone for a 10 days and will add fish after im back.
Does this sound like a good idea?

And good idea; I should use the powerhead to circulate the water.

Sounds like you've planned well, good luck. Tell us more about your system, size etc and whether you plan on running a sump and so on. Also check some of the tank build threads. One of the members here, Myka, has some excellent links in her signature with information on starting a tank, cycling etc. Here's a link to her 90 gallon build thread, as mentioned, the info links will be at the bottom of any of her posts in her signature area.

I checked at the LFS and they charged 45cents a gallon of RO/DI water. So about 40 bucks for my 80 gallons. If the DI unit is only $40, I might as well invest in one. How much would a good one cost, what brand should I look for and how would I hook it up to my house's drinking water? Some more info would be great!

Is the DI part of the process just another filter? I was planning on buying a single canister and putting a DI filter in it after the water has passed through my RO filter. Is this how it is done?
