Algae Research Supply Algae Research Supply Salts Spirulina Alkali Media, Makes 5 Gallons, Perfect for School Science Fairs/Projects, Experiments & Classrooms

I got this to replicate their smaller "brainy brine" kit, where you raise adult brine shrimp to adulthood. I emailed them to ask instead of the spirulina mix, if i could get the saltwater algea mix, which makes the perfect conditions for the shrimp. Not only did my brine shrimp grow to adulthood, but they lived on in my 5 gallon bucket for well over 6 months. (at this point, I think i may have crashed the culture by feeding too many to my fish!) A+ customer service and product! If you're looking to raise brine shrimp, message them and ask for the saltwater mix instead!

I originally bought their small kit to start our spirulina growing journey and it did beautifully. So I had to purchase this Culture Salts to expand that tiny culture. We are now in a 4 gallon square tank and the algae is growing so well. This purchase says it will make 5 gallons total. So far we made up a gallon of the mixture and it's lasting pretty well. Within a few weeks our spirulina was such a dark green and very healthy. It's almost time to start harvesting. I tried to get a picture, but the glare on the side of the tank was just too bad.
