Excellent question ;)

You are correct you do feed less the Dubai Mall case study showed this with a reduction in food bill per month from $10,000/month to $4,000/month

The food has no effects on PO4 the product is not fortified with ash found in the many of other foods, it also contains a Ferrous sulphate monohydrate (a PO4 binder.)

Ferrous sulphate monohydrate is a mineral additive. As a blood tonic substance to livestock, it can stimulate the growth of animal's body. source of iron, promotes oxygen-rich blood, immune support.

When the likes of Dubai Mall are throwing in over 20Kg a day, a food with a PO4 source would be very detrimental.

From an expense of $10K to $4k would be enough of an incentive for a business to switch food sources, if the health of the inhabitants could be maintained.:wink:
I am interested in further information of the PO4 binder you mentioned.
Phosphorous is of course an important macromineral.

Thanks

No Aquarium of that size would take on a food that did not equal or better wet fish which was used before. Each aquarium have in house marine biologists and nutritionists who test the food composition before use. Vitalis is the only food to meet these requirements.

The company cost saving is based on less food wastage and higher nutrition. Wet fish pulping produces a lot of waste also, they used wet fish as the only other option until vitalis came along.

If you google the ferrous compound for pet food it will give lots of info :-))

I bought some Vitalis (Marine Grazer) almost a year ago from an aquarium store in Kelowna. I feed it to both my freshwater and saltwater along with frozen. They always eat just as readily as the frozen. Btw, I keep all my fish food in the freezer or fridge for longevity.

How long do the marine grazers last? Has anyone used them in a tank with predatory fish that like to steal large food items and swim away with them? Worried my wrasses will rip it off the suction cup and hog it to themselves.

They are very dense and bulky unless we are dealing with something like an eel you will be fine. The grazers last 24 hours before breaking down, by then by a long shot they have been devoured

If feeding fresh water use either tropical grazers or cichlids grazer this way the species get the correct nutrients.

Later in March the holiday grazer launches, good for a week.

This review was done when it was called New Era, same food different name.
