Has anyone ever tried cultivating spirulina algae and adding it to a fry system in small doses as food??
Any opinions would be appreciated.
Please do not take in the growing of this algae, as I do have a source of live supply.
Thanks,
Mark

Maybe you could add it to the fry tank BEFORE you add the fry to boost the growth of natural algae on the glass which they fry will endlessly eat.

If you do plan on feeding the live stuff I would make sure there are no other 'nastys' in the mix that could harm your fry.

These could be unknowingly present if cultivated in outdoor conditions
