I have used Nualgi to grow Green Algae in a small tank.
The difference in growth rates is quite remarkable. Please see the photo.
I did not use Nualgi in the tank on the left and there is no growth visible after 3 days. The brown colour is due to the dung used as nutrient source.
The tank on right is very green. Just 10 ml of Nualgi has been used in it.
