Right now I've got Nannochloropsis and Tetraselmis in culture with Rhodomonas and T. Isochrysis on the way. Everything is in pure culture, but can be mixed prior to delivery/shipping.
Price: $15 per 2L bottle, $10 per 1L. This stuff can be kept in the fridge for a while too.
I'll also have rotifers available within the next month or so
