I gave AlgeaBarn a shot for the first time last week. My order included a jar of brine shrimp that never hatched. I contacted them about it and even followed the directions of leaving lid off for 48 hours and still only one ever hatched. Just beware that they do not send you another one for free because it is less than a $20 product. My options were we will add it free to your next order, give me pod points, or I could pay $12 to ship another jar. Needless to say, those options are just to get me to buy something else instead of fix the issue, and I will probably just stick with the company I was getting pods from to begin with.
