I've read a lot about Rod's food and decided to give it a try... normally i feed H2o Life Spirulina cubes to my tangs.. I have a tank with mostly tangs... I tried the Rod's food for herbivores... I've noticed that there's an awful lot of meaty content for something that was meant for herbivores... more meaty content than greens... large chunks of fish and shrimp... would this diet be OK for my tangs??? Seems more like a diet for carnivores... also, my nitrates are normally at 0 feeding h2o life but ever since i've switched over my nitrates have jumped to 10 in a week... I'm guessing my tangs aren't able to finish all these large chunks of meat and it's polluting my water... What's everyone else's experience with Rod's food?? Other than the self-blended home made food, what's everybody else feeding???
