Our nutritional products were developed for our use, initially with no intent on selling to consumers. We developed foods with one goal, to be a complete food. Meeting the nutritional needs 100% with no fillers and not skimping on expensive ingredients. This of course means it costs more to produce. But offsetting that cost we found substantial savings in time (we feed 300 tanks in 8 minutes), water changes (less filler less waste in the water), and the biggest factor was not feeding live food (which alone justifies the manufacturing cost of our food).
