What is the brand or manufacture's name of the "stop algae"? evolution aqua

I found the Evolution Aqua to be "Stop Blanketweed" pond treatment which is citric acid: http://www.hse.gov.uk/biocides/copr/approvals/approvals0608.pdf

[Rayscasa]

do i need a special kit to determine the ammonia

 

[Rayscasa]

should i had water softenor salt to the pond

 

[MitchM]

There is no reason to add salt to your pond at this point.

When did you first fill your pond with water and how soon after that did you add the fish?

.

 

[Rayscasa]

we put water in june 2015 and added the fish a week after that but i added more fish after that

 

[MitchM]

Your pond was stocked with fish too early, but it should be fully cycled by now.
I would buy an ammonia test kit and test the ammonia level.
Get liquid drop test kit instead of the test strips. Liquid test kits are more accurate.
The algae that was growing was actually helping improve the water quality, depending on how much algae you had.
Could you post a picture of your pond?
What is your water change routine?

You should have waited to add fish and the second set of fish should have been quarantined .They can carry diseases into the pond .Did the problem start after you added the second set of fish .Even plants should be quarantined

That's a good point sissy.
I so rarely add fish that I forget about quarantine.

[sissy]

Never added fish myself but I do quarantine plants and clean the roots and repot them .It is better to be safe than sorry .That is why even the baby fish I take out of the pond to be given away get put in a stock tank with a UV running just to make sure they are as healthy as I can keep them .But I make sure to tell people to quarantine them ,not sure they listen .Everything you put in your pond has some kind of effect on it .Fish are depending on you to keep them safe .
