Rayscasa, in the last picture, what is the vial on the left measuring? Is it chlorine?
Do you use straight tap water for your pond?

Also, what chemicals have you added to your pond?

.

 

[Rayscasa]

im new to this pond and this site so dont know if im posting it in the right place

 

[MitchM]

You're doing fine, Rayscasa.
Please answer the questions.

 

[Rayscasa]

it is for chlorine but i added tap water to the one on the left and pond water to the right and then added the solution for ph 6 drops in each
regarding adding tap water yes
treatment i put anti toxins in the water about two weeks ago
and i did add some stop algae

 

[MitchM]

Chlorine in tap water is a poison for fish, it will burn their gills.
You should be either treating the tap water before it goes into the pond or treat the pond water before you add the tap water.

Algae is good for your pond. It helps purify the water, but too much algae can cause problems.

What chemicals exactly did you put in your pond?

[MitchM]

It is difficult to help if we don't know what you put in your pond.

Chemicals put in ponds only add to the problem and does not solve anything it just makes it go from bad to worse .

 

[Rayscasa]
