FOR MICROALGAE ALGAE CULTURE KIT™ Complete mini algae culture kit for growing microalgae (greenwater) when you need them. No longer do you have to determine if the liquid algae you purchase is still good or alive? Each kit produces two quarts of live microalgae in 7 to 10 days. Microalgae is the primary food source of the food chain and ideal for feeding zooplankton (rotifers, artemia, daphnia etc.) and invertebrate filter feeders such as sponges, feather dusters, clams, oysters, scallops, corals etc. Our petri-dish cultures of live microalgae are specially sealed for extended shelf life. “Micro Algae Disk™” live algae cultures can survive for 6+ months when stored at normal room temperature and in low or dark lite area. Liquid microalgae cultures normally sold in pet markets actually live only 5 to 10 days while the actual number of live cells diminishes over time. NCP disks contain over 3 billion live cells of Nanochloropsus which can be grown in salt or freshwater. Whereas, our TET ( Tetraselmus) disk is strictly for saltwater use only. You can have two quarts of “greenwater” in just 7-15 days. Simply place a small amount of sterile culture water on disk, replace cover, provide moderate light, for 12 to 24 hours then rub off cells with a sterile cotton Que-tip (provided), add to 2 liters of culture water, fertilize (provided), aerate (attach rigid tube and airline provided), seal top of container to prevent contamination (Parafilm stretch film provided). Provide moderate to strong aeration. Light of 16 to 24 hours per day, (bright but not hot light). Maintain temperature of 73°-83°F (23°-28°C). More detailed instructions on microalgae and plankton culture can be obtained in our Plankton Culture Manual™ and see our other culture kits.
