Your pool probably has an algae issue. You can clear it up by giving it a good pool shock.
Keep the pH between 7.2 - 7.4 and TA 80 - 100.
Backwash twice per day until the water is clear. Vacuum and brush to loosen up any residual algae.
pH 7 and the colour green it is neutral.
Your pool water turned green immediately after adding pH Plus because the chemical had increased the pH level to high. You may need to adjust the alkalinity levels of the water using another pool chemical such as pH Minus of pH Alkalinity Plus.
The color is green for the universal indicator.
The pool turned green in Rio due to an imbalance in the pool's chemicals, specifically the pH levels, which caused algae to grow and give the water a green tint.
Bromothymol blue is green at a pH of 5.
Copper sulfate appears blue in color on the pH scale.
Green
a swimming pool it should be neutral pH ie green
The colour green refers to nuteral in the Scientific Ph scale.
On the pH-paper Meck art .9565 the acidic range color is green to red-brick.
When a pool turns green, the cause is the build up of algae. To remove the algae, chemicals will need to be bought to restore the PH levels in the pool, killing the algae.
Ph is up doesn't correlate with a clean pool. The pH needs to be lower to get it clean. And then you need chlorine, probably lots of it to get it clean; try 8 gallons of liquid or 20lbs of tricolor. Trichlor is good for white plaster pools. If you have a colored plaster, it would be better to use Dichlor.
