Also, was it difficult to set up your RODI to your ATO? Do you have float valves to auto on/off?Lots of people, including myself, have run successful marine aquariums without owning an RO/DI. Some folks really do have good enough water quality that they just don't need one (rare, but it happens), some folks would rather carry buckets from the LFS (small tanks, I'd guess!), and some folks use a non-RO type filter (Culligan, etc). Even met a few that bought distilled water.
Others, like myself, just suffered with algae problems... until I bought that RO/DI unit.
IMHO, if you're going to own a reef tank, an RO/DI filter is a very SMALL percentage of what the system as a whole will cost, and will make a HUGE difference in the likelihood of success, in a hobby where the vast majority of newcomers don't last very long.
These days, my RO is plumbed to a pressure tank under the sink, providing filtered drinking water at the sink, and chilled water at the fridge, even ice cubes are made from RO filtered water. Post DI, it's plumbed directly to my ATO system, and to my AWC reservoir... I use the heck out of my RO/DI system, can't imagine not having one.
