LF - Powerheads/Heaters

[molotov]

Hello,

I'm new to this forum and saltwater aquariums. I've recently purchased a 100G tank and a 30G sump. The setup also included a pump, stand, current USA lights. I found a brand new in the box Red Sea C-Skim. I'm still trying to piece everything together and am still looking for powerheads and a couple of heaters. I believe I will also need a RO/DI unit.

If anyone can help with my shopping list I would greatly appreciate it. Also any other suggestions anyone can offer would be greatly appreciated.
