Lights depend on what corals or clams you are going to keep. MH and VHO actinic is prbably the way to go IMO. Use a factor of >100 watts per square foot as a starting point for planning purposes for SPS.

Look at a fairly small flow through your sump and fuge and do the majority of the tank flow going through your closed loop.

For a tank that size with SPS you need to look at something like a calcium reactor for supplements.

Scratch iodine from the list.
On the sand bed, I didn't factor in the size of the tank. Origionally I was looking at a 250 gallon tank and everything I read says "I wish I had a bigger tank". So when I upgraded size, I forgot the sand. Thanks

Nice point on the flow through the refuge/skimmer. What flow do you recommend through these vs. the closed loop. I have read that you want the tank to process through 1.5 - 2 times an hour. Iws this still a good rule for the refuge/skimmer with the closed loop?

Thanks for the confirmation on the calcium reactor. What brand / size flow should I be looking at?

Even if I want to have some pistol shrimp with my gobies I do not need iodine? Do the salt mix and other stuff have enough iodine for them? I know iodine can be trouble if too much is input.

Thanks GaryP for the input.
