Hi Crook. All corals should be given other foods. Phytoplankton is what you want to feed your corals. Liquid Life has good food. The bottles are small; kept in the freezer (and yes it is liquid...even in the freezer) but it is concentrated. Three drops two to three times a week is enough to satisfy a 60 gallon reef. Liquid Life foods have three different size foods to fit all different types of coral. There are also DT's...a live culture of phytoplankton. Less expensive, only one size food, and you need to dose more of it. Good to mix with Marine Snow. Cyclopeze is another good food to add to the mix. Feed the coral a few times a week. If you have any deep reef coral like carnations, chillies, gorgonias and sun corals, then daily target feeding is recommended. This is when you use a dropper to push a cloud of food directly on the coral.
You'll start to see all your coral blossom!!...especially with that marine snow stuff added in with the phytoplankton. Really beefs them up good.
We, as a people, know so much more about outer space than we do about our own oceans. This lack of knowledge can very well spell the dangers that lay in wait for us.
The oceans surely would swallow us before a rock comes down to smite the planet of it's life.
