There are way too many to list but Coral Frenzy Powder and Oyster feast come to mind. Almost any reef company has their own food.wich products give similar ratio?
There are a ton of whole live pod foods available as well which to me is even better. You stock your tank with live pods, they breed and then the micro plankton they produce is a much more natural food and you don't get a P04 spike.
The phyto would still be part of the cycle creating food for live micro pods.
There are many companies that sell this type of live food like Algae Barn.
There isn't any scientific evidence that SPS consume a certain micron size so I'm not even sure how important size is but even hatched brine shrimp is plenty small enough. I believe Sps rely more on absorption than actual prey capture, but that is a whole other discussion.
LIke I said this product's sell is convenience but it's not even close to the only one out there that can be hooked up to a doser.
Anyone can also smash up their own raw foods and create a slurry for corals.
These will probably cause more of a P04 spike but there have been plenty of people that did this going back 10- 15 years or so. Blue Coral method was very popular back then.
Micron coral foods have been around for a few decades.
Again, I'm not knocking Easy Sps...........if it works that's great.
