    Hi,

    I’m growing Spirulina on a very basic budget and don’t have access to a microscope. I am slightly worried about contamination and it seems others have only been able to tell if their culture is contaminated by seeing foreign bodies through a microscope. What other indicators are there that the culture is contaminated? e.g. colour, pH etc.

    And can the majority of contaminants simply be killed by increasing the pH to around 10-11 (by adding more Sodium Bicarbonate)?

    Thanks!

    I have read that if the color changes to some yellow or if there are some brown like falling at the bottom these may alert for contamination .
