Answer

Daphnia should be used within two weeks of purchase. If required for a longer period, place into fresh water after this time - using pond water, bottled still water or rain water (NOT tap water) - and feed with Daphnia food (BLO-200-120), Chlorella (BLO-050-100) or other algae. On receipt of the Daphnia, pour them gently into a large beaker, tank or other container and keep cool (10-15C if possible) and out of direct sunlight.
