So I’ve been reading various forums and websites and I have been trying to understand two things:
(1) How often do you feed nutrients to the spirulina?
Some background info: I’ve had a culture now for 3 weeks and just went on to double it from 1L to 2L by removing 250mL from the original batch and created a new nutrient medium of 750mL. The original batch I replenished it with 250mL of dechlorinated water and added the proportion of nutrient mix that you would find diluted in 250mL of a 1L Happy Spirulina solution.
(2) Did I do the right thing?
One last question, I run bubbler (set very low) during the day and turn it off at night. The water temperature is around 28 deg C during the day and lower it to 22 degrees C at night.
– Is this ok or does the spirulina need no stress (no heat, no bubbling) during the night time?
