I am recently experiencing a renewed bloom of BBA in my aquarium. So now that I have the raw material I can plan the experiments.
General details
After I pick mature BBA from the aquarium I put them into small covered glass containers. They will be monitored and photographed. I will consider them growing if they are increasing in size or new algae colonies are observable. I will consider them "dead" if the algae is white-transparent or red and does not recover after 1 week. The light will be coming from a west window ( spectrum and amount does not matter for these experiments). All the water has a starting concentration of :
NO3 15 ppm, PO4 2.7 ppm, 11.2 ppm, 0.4 ppm Mg. Tap water has a reported GH 13, KH 11.
Controls: 2 bottles with tap water exposed to light
Experiment 1: Simply keep the algae samples in the dark for 3,5,10,15,20 days. After the darkness period re-expose to normal light and observe.
Experiment 2: Put algae in pure RO, 1/2 RO-tap, GH=4 KH=0
Experiment 3:Treat with Easylife Carbo at 1x, 2x, 5x, 10x
The problems with this experiment incluse the lack of organic substances from a normal aquarium. Lack of water movement... accepting donations to buy mixers or agitators.
Do you see any problems or confounders ?
What other tests would you like to add ?
