 ==Making it glow==
-'Pyrocystis Fusiformis' can easily glow. A small disturbance in the water will make it happen. For the purpose of my project, I wanted to find a gentle way to make them glow, with the most amount of light emission.

 *'''Electromagnetic Stirrer'''
 The electromagnetic stirrer was definitely not my favorite even though it works well. It creates this cyclone which could be highly aesthetic, but at the same time it creates a uniformity in the water. The water becomes blue-cyan and you don't really see all the small dots that for me is much more interesting. It fades out too much the organism by giving more importance to the water that looks like it is glowing.
-If you still use it, be careful on the power you use as the 'Pyrocystis' get exhausted quite fast with this technique. It was also another reason for not using it for my installation.

 *'''Air Pump'''
+The air pump was for me the most interesting and conclusive one. The amount of light is quite high and the individual organisms are still very visible. Moreover the amount of bubbles can be adjusted by the voltage of the pump, and the stone that is used at the end of the tube. It has an nice aesthetic but most importantly, I believe it to be the most ethical one of these choices. It is definitely less violent than the other ones. Actually, air streams are common in their natural habitat and air is something they need to stay alive. It has also a conceptual meaning as the algae filter air and produce oxygen the same way trees do.
+For the installation, I used a 12V pump, but any aquarium pump could definitely do the job.

-'''Note''': As our bared eyes can see the glowing perfectly, taking a photo of it more complicated as it needs a long exposure. To make a video of it is even more difficult.
