I have been using Brine Shrimp Direct's Cool Color flake food for three months now and I like it. The number one reason is price. $13.95 for a full pound container ! You can't beat that price with a stick. What differentiates this flake food from others is the manufacturing method. This is dried rather than baked to a crisp thus preserving nutrients. BSD recommends using this all within 6 months and I probably got too big a thing of it , but what the hey , I'll feed them really good and use it up ! The first thing you notice when you open it up is the smell. This stuff is strong and really smells like good fish food. They have other varieties and formulations and next time I think I'll try the organic earthworm kind. My fish go wild for this and scavenge out every morsel eagerly. No free shipping with Brine Shrimp Direct but that is nominal. My last order came to $33.35 for this pound container and 1.75 ounces of Premium Grade Artemis cysts. Can't complain. If you are looking for anything brine shrimp related they have it all. BSD is a small hobbyist owned and run operation so they take this stuff seriously. Give them a try.
