Every week I refill this jar to dechlorinate water for my aquariums.
Dark green algae grows on the walls of this jar.
Chlorine does not kill all algae!

I fill up 4 jars with New York City cold tap water.
New York tap water is disinfected with chlorine.
It takes 24 hours for chlorine to evaporate from open water.
I keep open jars on a windowsill.

Add gravel and driftwood into the 2nd jar.
A rooted cutting of Wandering Jew plant goes into the 3rd jar.
Gravel with driftwood goes into the 4th jar (as in the 2nd jar).
2 bladder snails go into the 4th jar.
Add a pinch of fish food flakes into the 4th jar for snails to eat.
So, here we have 4 jars with dechlorinated water.
The 2nd jar with water, rocks and driftwood.
The 3rd jar with water and a plant.
The 4th jar with water, rocks, driftwood, snails and fish food.

Cover jars to reduce evaporation.

July 12th, 2018
In the past month water remains clean in the 1st, the 2nd and the 4th jars.
It gets cleaner in the 3rd jar.
Also, I replaced the Wandering Jew plant with two Frogbit plants.
I have a number of conclusions based on these experiments.
One is rather obvious: keep aquariums well planted to reduce and prevent algae bloom.
Have fun and happy aquariums :)
