2 things cause the green water.
1st one is green algae problem and the 2nd one is copper.
Since, you have been used the algaecaide there is one reason that can be missing and it is copper.
I've checked your test results but there is no information about copper.
The copper level at the water has to be 0.
I would recommend you to test your water about copper and if you find out the copper level is more than 0 use stain magnet from glb. dont forget to follow the instructions from the label of the product. you need tou adjust your pH.
Take care
