I was at a LFS and bought some Algagen Pods and noticed that the date was 8/22/17 and has a 4 week expiration date. I dumped them in with the wavemaker off and did not notice anything "squiggling" around. Granted I have poor eyesight but shouldn't I have seen something move? Also does anyone know what the algae they include in the bag is? Is Chaeto or anything beneficial? I put it in my fuge and it looks kinda black and sank to the bottom. I haven't turned on the grow lights yet but have them.
