http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=foul-odor-in-my-freshwater-aquarium#1 I have just got a tank with seven goldfish to start with. It has been only a week and a very foul odor is coming from the tank and I am unable to figure out the problem. Ern original post: April 19, 2007, 5:06 am anonymous 2008-05-02 http://forum.aqua-fish.net/?topic=foul-odor-in-my-freshwater-aquarium#2 And what everything you have in that aquarium? And how strong filter you have? The odor can be the normal odor of the aquarium, but it isn´t very strong. Then it may be the excrements of the fish or the water. Mostly you get rid of it with a adequate strong filter. Lilium 2008-05-02
