So spirulina is algae based i am led to believe so if i were to add this to water finely crushed and mix it up and put gravel from my tank in it will this make the algae grow faster??if i put it under direct sunlight or any light that is?
i have a pleco and some snails and want them to be able to have some food if i leave for a few days plus i heard its good for fish to have to eat if gone as well...ill be gone for a week and although ppl say tht fish can go a week without eating i dont wanna risk it and i dont have the cash to buy an automatic feeder right now and i dont have someone to feed my fish for me
will algae increase the rate that snails multiply?

and will it be beneficial to guppy molly and platy fry?
