The plan is to use reef tank water every 3 days, as it has enough nutrients that I shouldn't have to feed the little tank at all. But I do appreciate your input, <b>waterfaller1</b>. Since I've never done it before and you have, you have more experience in this case. 
I'm going to keep an eye on it. If I can keep the main reef's water in good shape parameter-wise, I'm hoping that water will work out for the Pico. Using newly mixed or even aged saltwater may have the right numbers but the water would be nutrient free and the corals wouldn't get any food at all - just what they could get from the light. Since I don't have any filtration other than the what the two clams can process, I don't want the tank to get polluted.
Maybe the 2g Pico needs a 1g sump.
