PixelBattery Posted February 22, 2017 Share Posted February 22, 2017 Quote Algae grow when they have the right conditions such as adequate nutrients (mostly phosphorus but nitrogen is important too), light levels, pH, temperature, etc. Generally the amount of phosphorus controls the amount of algae found in a freshwater lake or water body. It would be good if you could grow algae on your own. I did read on the forum that algae is supposed to help you out at the start until you can produce oxygen in an other way. But it would still be nice to have other alternatives once you run out of algae. Even if it only grows slowly Link to comment Share on other sites More sharing options...
