Food Source

I've been growing algae for my algae-eater fish in my aquarium. Algae requires light to grow. I don't know what water temperature is best for algae, though I'm sure warm is better than cold. My solution for growing algae is very simply. I've placed two dozen quartz rocks into a five gallon bucket. I've filled the bucket with tap water, and placed the bucket in the backyard in a location that gets the most sunshine. I use quartz rocks so I can see the algae growing on the white rock. As water evaporates from the bucket, I add more water. In two months, the water is probably too alkaline for the algae, so I change out the water. My algae-eater fish love the algae covered rocks.

I was thinking the same thing about algae as a source of food for people. I don't know, can people eat algae?

I don't think algae grow quickly enough to be food under normal circumstances. Not eating algae at all is an option, otherwise change the circumstances. More light and more nutrition in the water would stimulant algae growth. There are cold water and warm water algae, sea water and fresh water algae.

Most definantly. I know of several varieties (spirulina, sun chlorella and super blue-green algae to name a few) that are used in the health food industry to supply minerals, vitamins and other vitally needed basic nutrients. These being classed as super-foods. There may be other varieties. How to grow these is a subject we all need to know more about.
