I'd be glad to answer some of your questions
A) We say that it will not rapidly degrade water quality. You are correct all nutrient input will eventually breakdown if it is not consumed. But because of the ability of the product to stay in the water column for extended periods of time, most of the product will be consumed by a filter feeder before it can break down.
In contrast, almost all other "coral foods" are made from what you could consider "ground-up flake fish food". Any kind of food that is made from this kind of fish meal or "hydrolyzed fish protein" will break down into dissolved organics very quickly. This is a result of the process to produce fish meal.
As a crude analogy, imagine throwing a cooked sphere of steak into some a lake versus throwing in an cooked meatball. Both of them being the same size (Wow this is a REALLY crude analogy!) But... which one do you think would take the longest to break down? The steak will last the longest because the proteins holding it together have not been broken up. The meatball has been chopped up and will break down into it's smaller parts of ground beef.
B) In comparison to any other coral food available, I would highly recommend Reef-roids for a skimmer less aquarium. It is difficult to run your water quality with the product. To put things into perspective, I have accidently knocked over a full canister of Reef-roids into a 90G test aquarium. The canister was sitting on the plastic cross bracing on the tank, and I was distracted by a co-worker and when I turned around, I knocked it in. At first, I panicked (thinking I should siphon as much out and do a massive water change) but I decided to leave it in there and to see what would happen. The water was a reddish haze for the first few days but Over the course of 4 days, the water cleared up and almost all of the product had been removed by the skimmer. (There was still some of the product floating on the edges of the tank). But most surprisingly, there was no algae bloom. None. No inhabitant deaths. And no corals or fish seemed to be affected. I measured nitrates and phosphates with salifert kits and it was literally exactly the same as it was before I knocked it over. 4ppm nitrates and 0 phosphates. (The salifert test kit is not the most precise for phosphate readings but that is all we had in the lab at the time)
B) The product does not contain any preservatives. It is composed of a few types of naturally occuring marine planktons and a zooplankton strain. The exact stain of zooplankton is proprietary to our company but it was selected to be used in our product because of it's incredibly nutritional characteristics. There is no other product on the market that uses this particular strain of zooplankton. There is nothing else in the product. There are no sugars added. Saccharides are a type of sugar and there is certainly none of that added in there. Gluconates and polygluconates are also not used in our product.
C) The product has been tested for both organic and inorganic phosphorous. It does contain extremely small amounts of both. The values are so low that we needed to use fairly expensive sorption balance test to get readings. These trace amounts will have absolutely no effect on your aquarium water quality. I do not have the numbers on hand but I can ask one of the lab techs tomorrow to see if they kept a record of it. If not I can ask them to re-run the tests for you when we have some time.
If there are any questions I can answer for you, or if you need any other information, please just ask and one of us here will do our best to answer them =)
