The live sand is the bagged kind that I used, 120 lbs of it. I get RO water from a couple LFS since I do not have a RO/DI unit yet (soon). If you want names PM me plz. For food, I am using several things. I have no corals besides mushrooms, so I use Marine One flakes, Marine One kelp flakes, frozen mysis, marine cuisine, and H2O Life spirulina with brine shrimp and mysis. Then of course I use red nori for the bigger fish maybe every other day. Oh, I only use this once in a while, but it is dry hatchery diet from Sustained Aquatics. The clowns go nuts over it. I do not feed much of it when I use it which is maybe once every 3-4 days. The rest of the foods is mixed, whatever I happen to grab. They are not all at once. I feed once in the morning, say a cube, then another cube at night. Or it might be some flake then a cube at night. You get the idea. Like I said though, I probably am over feeding and will take your advice and try cutting down some. They're such pigs though lol
