Bringing this thread back since I just got some Reef Frenzy and used it for the first time tonite.
I've been using Rod's Food for a few years now and was interested in seeing if there was much difference.
First impression.... I need more impressions.
Tomorrow I will feed Rod's again to double check, but when i put the Reef Frenzy in the tank there were two things that seemed to stand out to me. For one, the Rod's seems much denser than the RF. I noticed this in the package. The Rod's is very dark compared to the RF, making the RF "seem" like it might have more water content? But that's just a visual observation. When i put the RF in the tank, I felt like I wasn't getting as much dispersion and amount of food flowing into the water column as with the Rod's. Almost like it was "cleaner" and was completely gone in seconds. But not because the fish went crazy over it, in fact it seemed like some didn't even get a chance. There really did seem to be less of it. Also, there were some bigger chuncks that didn't break up until a fish attacked it.
So when i was done pouring the food into the tank (mixed with tank water and some Oyster Feast) I stepped back and the water was almost completely clear! Usually there is lots of little specs all over the tank. This is kind of what i mean about it being cleaner. But I'm not seeing that as a good thing. I see all those little specs as coral food.
In the end, I felt like I needed to go back and supplement with some of my New Era Marine Pellets, which the fish eagerly attacked.
So as of first use, i'm feeling like the Rod's is packed with a lot more stuff in the same 1" square piece of food. Will continue to experiment and report back but would be interested in thoughts from anyone else who has experience using both foods.
