As for my favourite product. . . it depends on what I'm feeding. For tropical fish I like the microwafers, for carnivores I like the carnivore or massivore pellets depending on the size of the fish. I like the algae wafers for algae eaters and the bottom feeder pellets for other bottom feeders.
I don't have a favourite one product.
I prefer their algae wafers to most other brands. But I prefer NLS to their microwafers for tropicals because I can get more variety. For the carnivores I had, I fed a mix of bottom feeder pellets, carnviore pellets, cichlid biogold, frozen mysis, frozen bloodworms and live blackworms. I couldn't say any one of those was better than the other.
