Rinse frozen food or not?

No doubt it has phosphates, but I believe that adding a couple of ounces of it to a 120 gallon system will have a negligible affect. And besides thats why I run gfo and bio-pellets.

The cloudy water is full of phosphates. Run a test and put in a drop and you'll see how much there is. My color changed drastically and since then ive always rinsed

I've always always rinsed. Never dared to think about putting a cube in without rinsing! The stuff that runs out probably feeds the algae more than the corals.
I target feed my corals whatever I feed my fish.

Same method as others. Place the cube in a fine mesh and run tap water through it until water runs clear.

I'm surprised this many people don't rinse.
