What's up with that? Last friday, I added a new plant in my aquarium (so now I have 2 nice beautiful live plants in there!) To do so, I removed my "castle" whilst placing it in and put it on the table. Since I've put it back, the algae on it has been turning white. Is it: a) The algae was buggered because of being outside of water for...10 minutes? b) The combined demands of the 2 plants is getting to the algae? c) Something is not quite right..
