I am culturing phytoplankton that at about 9 days, it declines, so I have to harvest it. I have watched too many videos and searched all over R2R but I cannot find how to make my phytoplankton darker/denser.
Should I increase saltwater and 2nd dose the F/2 fertilizer?
LFS suggested trying adding CO2 which makes me wonder what the pH would turn?
Suggestions?
My setup is 1 gallon containers. 80% full of 1.020 saltwater. 2ml of F/2. 4-5 oz of starter phyto culture. Lights on 24/7.
