Yup, I use it and like it. The fish take it readily, it seems to be easily digestible and there seems to be less waste when feeding it. Some have claimed to get better colors, but I have noticed anything terribly dramatic.
I switched my cichlids to it and I could not believe the difference in their colors! the peacocks were so bright, the yellow one looked like he'd been rolled in sulphur dust -- he had been just a muddy yellow with purple before. The frontosa got sparkles in the white stripes. All the fish looked better.
Don't worry about the cost, it is more dense than other foods and so you will use it more slowly.
No, unfortunately i odered my NLS from petsolutions.com before Neil decided to start bringing it into canada. But i will definately be ordering from him in the future He has been talking about bring NLS in for a while and i'm glad he finally took the plunge and did it.
