Wow that must be quite expensive. I have NLS, hikari, and Ken's food. I've had the NLS for over a year and have barely used it. IDK just not quite happy with it for some reason compared to the hikari. I will have to use it once I run out of the hikari. Out of hikari I have used micropellets, algae wafers, and the cory wafers. Usually only buy hikari when I am given a giftcard for petsmart, then I make them price match it. I am phasing over to the Ken's food. Super cheap and never had a problem with it. Bought like 1.5 pounds, 3 different kinds for $20 shipped a while back. I freeze a lot of my dry foods because I have at least a 2 year supplyi did use it but find NLS from the US is better, healthier and cheaper . Buy in bulk few times a year.
