Freshwater algae "green water" culture

Aeration required to keep this one in suspension, <a href="https://dorasaquatics.nyc/live-cultures/no-air-green-water-8oz">see the no-aeration type</a> if you need something that just requires lighting. Excellent food for microfauna and infusoria like daphnia, moina, copepods, rotifers, and more. Needs aeration and strong lighting, and occasionally to be split and fed with fertilizer -- either 1mL of F/2 Algae Food or a few granules of Miracle-Gro.

Grows well in local soft water. Hardy culture that can grow very densely (see pictures). And can also be kept in the fridge for a week or two to pause growth while you're away on vacation.
