These “DIY aquariums” actually prevented Sea-Monkey life after week 4.5. The jars varied in diameters of 2.25”, 2.5”, 3.0”, and 3.5”. The 3.0” diameter jar briefly showed a few nauplii but they died before week 4.5. So, these 16 oz. jars failed to grow Sea-Monkeys no matter their diameter. I had hypothesized that the jar diameter would be critical for Sea-Monkey growth, thinking the bigger the diameter the greater the dissolved oxygen that promoted Sea-Monkey growth. However, the jar diameter had no positive effect on raising sea-Monkeys. I wondered if the colored crushed glass in the jar poisoned growth and tried a 2.25” jam jar without colored crushed glass. However, still no Sea-Monkeys hatched.
