A buffer.
An indicator is a substance that changes color based on the pH of a solution. It shifts its color based on whether the solution is acidic, neutral, or basic. Examples of indicators include litmus, phenolphthalein, and bromothymol blue.
Buffers help maintain a stable pH level in a solution by resisting changes in pH when acids or bases are added. They can absorb excess hydrogen ions (H) or hydroxide ions (OH-) to prevent drastic shifts in pH.
When the pH starts to drop, a buffer will resist the change by absorbing excess H+ ions or releasing OH- ions to help maintain a relatively stable pH level. The buffer's ability to neutralize the added acid prevent drastic shifts in pH.
The pH range over which an indicator changes color is its transition range. This is the range of pH values over which the indicator molecule shifts between its acidic and basic forms, resulting in a visible color change.
Citric acid buffer helps maintain a stable pH level in a solution by resisting changes in acidity or alkalinity. It can accept or donate hydrogen ions to prevent drastic shifts in pH when acids or bases are added to the solution.
It simply not accurate enough .
A buffer.
Adjusts pH upward. Sodium hydroxide can also be used if necessary--for large pH shifts or very large batches.
Ph of distilled water should be 7.But due to the presence of chlorine & alumina in trace amounts to kill the bacteria the pH shifts. We know hydrochloric acid is stronger than aluminum hydroxide thus the pH is 6.
No, the juice has high levels of citric acid which makes pH for acid higher and thus unsuitable for microorganisms to grow.

There are a couple of things you can do to control the pH of the water for tropical fish. You can for example drain the water and start over.
