Live Phytoplankton saltwater culture / HELP

[monocus]

take the nanocloropus,add the same amount of water,and add a couple of drops of micro algae grow.start your experiment with your yeast culture co2 and don't add anymore micro algae grow.in another container do the same as above,but add a few drops of micro algae grow daily-you now have two cultures-1 being fed and the other relying on just co2.you can make a density stick for counting your cultures by using a small plastic ruler with a small 1/2" dot or stripe painted on the end-doesn't matter what colour.for every centimeter that you can see on the ruler before the dot dissapears will tell you how much your culture is growing.1 cm=27.6 2cm=19.2 3cm=13.3 4cm=8.8 5cm=5.2 6cm=2.9-these are millions of cells for nanochloropus.you can measure this daily and record your results,but wash off the ruler or better yet get two rulers and never mix your cultures.
