Bill, I will try the worm test this afternoon and I'll let you know. The catfish have really gone crazy over this feed and they are eating more of it.It look like there is no going back now.

Brian, how long have you been feeding the aquamax 600 to your fish and have you really noticed a difference in growth. AS you know by reading the above posts, I have just recently started using the aquamax. Hope the expense is worth it!!! I will be putting stripers in this fall and want to just feed on type of food.
