I asked them why they don't used substrate and the owner explain to me that it cause nitrate and phospate high. So I'm still gathering information about whether I do it or don't do it. Any suggestion between the two. Also when u feed your coral and fish how much do you place it into the tank and the how do you keep the debritus so that it doesn't get at the bottom and top of the sand.
Thanx

Well Jay, I have non readable phosphate levels. But my nitrates stay around <10 which is perfectly acceptable for a reef tank. Very few tanks can honestly say that they have zero nitrates with fish in them. I do run some carbon, changed every 14 days, and chemi pure to help with any coral allelopathy. Carbon gets a bad rap, but if replaced frequently it doesn't have a chance to release what it took out back in the tank. Water changes help tremendously to reduce the ppm of nitrates, and an excellent skimmer. I prefer the natural look of a tank with sand in it. But, I have seen many beautiful tanks with bare bottoms. I think that if you commit to having a large tank, then husbandry needs to be addressed. Are you the type to do frequent water changes? Or just sit back and wonder why things are going wrong without any water changes? If you can honestly answer yes to wc's, then going with sand should be the way to go. Just be sure to have at least 3 inches of sand, or more in the tank. This helps to break down unwanted nutrients.
As far as the feeding of the fish. My fish are absolute pigs! I feed once daily. Alternate between algae based flake, and frozen. I have to distract the fish to add sinking pellets for the bottom dwellers. They also get 2 1" by 3" strips of nori. I really should do a video of the tangs at feeding....they attack the nori with such a vengance. Very little if any food ever gets to the bottom, this is why I must feed the bottom guys. I don't even bother with the clips, they literally will take it out of my hand. Hope this helps.
