i think i learned something with culturing Rotifers this week. dont mistakenly feed them a large dose of Micro Algae Grow thinking it was Roti-Rich. i have a gallon of gunk, and phytoplankton that im will not be using. i have not seen a single Rotifer in the 3/4 of a gallon of water i screened either. luckily i have 2 gallons of Rotifers still going to split into a fresh culture. OOPS.
