A Strange Yet Pleasant Aquarium Smell

So hopefully this is a quick and easy question.... Has anyone ever experienced a sweet and spicy yet earthy smell coming from they're aquarium, it's pleasant but strange.... What could have caused this I have done a 30% water change yesterday and I can still smell it today. The only thing I can think of is that I put some new plants in there such as java fern anubias süßwassertang and some sprigs of moss all these plants came from a high-tech grower who is extremely knowledgeable. I would contact him and ask but I believe he's out of the country right now.

 

Lol yes I know the smell. It’s likely from either your plants, or some sort of nitrogen compounds.

 

Yep the more plants I add, the stronger it gets. More noticeable after I added sand as well.

 

I absolutely love the smell I just wanted to make sure it was safe for my aquarium LOL

 

I think it smells like a lake.

 

I think it smells like a lake.

My fiance's tank smells like a lake mine is all sweet spicy lol maybe it's because my fish are super sassy LOL

 

I think it smells like a lake.

One of the greatest smells in the world!

 

Its a good way to keep track of your tank. If it doesn't smell good somethings wrong and the worse it smells the bigger the problem.

 

My tank is a combination of eco complete and various plants. Eco complete smells really strange fry, but in the water it smells amazing. Could be the plants.... or the poop....
