cichlid2006;2936268; said:its not an ingredient. its the amount of ash left if the product was burned. google it there are various pages on it. its a way of analysing a product to see how much waste is left if it was burned. the less ash the better.
Googling I got more results that ash was an additive than the end byproduct

this being what looks like a good article. So still confused, if I go on the what I read, ash used to be what was left if you burnt it up but now days its used as an additive (from burnt bone etc) to provide extra nurtition for piscivores?


Sorry for the OT
