Algae Control


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!

 March 25th, 2018
 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.

March 26th, 2018
 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.

March 27th, 2018
 I add dechlorinated water to level into all four jars.


Cover jars to reduce evaporation.
The 3rd jar remains uncovered.

 March 28th, 2018
 I add rocks and driftwood into the 3rd jar.





 A pinch of fish food flakes goes into the 2nd, the 3rd, and the 4th jar.


Water is the same clarity in all jars.

 April 3rd, 2018
Add water to level into the 3rd jar.


Subtle water discoloration in all, but the 1st jar.

April 6th, 2018
 The 1st jar remains visually clean.

Green algae grows on the bottom of the 2nd jar.

Water is slightly yellowish in the 3rd and the 4th jar.



 April 8th, 2018
Add water to the 3rd jar.





More algae grows on the walls of the 2nd jar.

Roots of the plant grow longer.
 Water is yellowish in the 3rd and the 4th jar.



 April 15th, 2018
Add water to the 3rd jar.




Algae grows in the 2nd and the 3rd jar making water cloudy in both jars.


The 4th jar looks cleaner.
There are a couple baby snails.


April 23rd, 2018
 The 1st jar remains clean.

There are seed shrimps in the 2nd jar!
Most likely, they got in with the piece of driftwood.

Roots of the plant gets longer and are covered with algae.


There are many snails in the 4th jar.


 April 28th, 2018
 Added water in all aquariums.
 Water in jars with algae seems to get less cloudy.

May 5th, 2018
Hair algae grows on the old snail.

Greenish residue accumulates in jars with algae.



May 12th, 2018
 Snails population declines.

 There is more algae on the roots.

The 2nd jar looks cleaner.
 I don't see seed shrimps here.


May 18th, 2018
Seed shrimps are in the 4th jar!



Water gets greener in the 3rd jar.

Cotton-like algae grows on the bottom of the 2nd jar.

 May 23rd, 2018

 Seed shrimps multiplied in the 4th jar.

Algae covers the roots of the plant in the 3rd jar. 

 May 28th, 2018
 I am setting up the 1st jar with the goal of preventing algae growth.


Add gravel and moss in the 1st jar.


 Add moss to the 4th jar.
I use fast growing land moss in this example.

 May 30th, 2018
Water in the 2nd jar is clear.
  


Add a snail and a pinch of fish food in the 1st jar.


  June 1st, 2018
Seed shrimps are in the 1st jar...and I am not surprised at all.


 June 3rd, 2018
Add a pinch of fish food flakes to the 1st jar.



Population of seed shrimps grow in all but the 2nd jar.

June 11th, 2018
 I feed the snail in the 1st jar once a week.

June 13th, 2018
Add driftwood to the 1st jar.
The 1st and the 4th jars have everything about the same, but they were set in different orders!




 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 :)
