Sorry to keep you guys waiting as I just finished conducting water changes for my giant tanks and my Pleco tank.
Setting up the test!
Ktp juice in the test tube!
KETAPANG JUICE IS INDEED ACIDIC. PH 5!
To further on carry out another test I combine the ktp juice and the other bottle of tap water into a pet container to demonstrate the effect
As you can see the combined ktp juice + tap water the colour is lighter
The result is still acidic. The red is lighter.
