Greenwater

$29.99Price
Live multi-species freshwater phytoplankton — for daphnia, moina, copepods, fish fry, and outdoor pond inoculation.
 
WHAT IT’S FOR
  • Live food for daphnia, moina, copepods, and rotifers — highly nutritious, doesn’t foul the culture water like prepared foods do
  • First-food for fish fry — microscopic cells stay suspended and feed the infusoria fry consume
  • Outdoor pond, lake, and waterway inoculation — absorbs excess nitrogen and phosphates, oxygenates the water, and feeds the bottom of the food chain
  • Not for indoor freshwater display aquariums — phytoplankton can bloom in tank water and cause discoloration depending on your nutrient and lighting setup
 
WHAT IT DOES IN PONDS & LAKES
  • Absorbs excess nitrogen and phosphate until depleted
  • Consumes carbon dioxide and produces oxygen as a photosynthesis byproduct
  • Reproduces continuously, providing an ongoing food source for daphnia, moina, copepods, minnows, and fingerlings
  • Improves water quality and supports a thriving aquatic food web
 
WHAT’S IN THE BOTTLE
Live, monospecies-cultured freshwater phytoplankton in a clear bottle, cared for in closed-system photobioreactors with controlled nutrients, minerals, and lighting. Available in single bottle, 3-pack, and 5-pack sizes.
 
HOW TO USE
Acclimate the bottle to the temperature of your destination water (float the bottle for 30 minutes if outdoor pond temperature differs significantly). Once acclimated, add the entire bottle directly to your culture or pond. For outdoor ponds, dispense as far from the shoreline as possible so cells don’t wash ashore. If you can’t use the entire bottle right away, store the remainder in a separate container with light aeration and a strong light source to keep cells active.
