"A half cup of water at 1 ppm (1 mg/L) phosphate contains a total of 0.12 mg of phosphate. A cube of Formula 2 contains about 11.2 mg of phosphate. So the hypothetical rinsing step has removed about 1 percent of the phosphate in that food. Not really worthwhile, in my opinion, but that decision is one every aquarist can make for themselves."
Thats the part that concretes it for me. I've never rinsed frozen food, simply because its effects are negligible and the phosphates are going to get in there anyway. Plus the feeding response from my corals is greater when the fine particles are left in the tank.
Granted, I prepare my own frozen food, but there is some mysis in there, and cyclop eeze, both of which go into the mix unrinsed. I have never had any algae issues as a result.
