pH issue... Again

[littlehermit0]

7.4??? I refuse to believe this like I'm serious I don't think this is actually real

i changed my mind, salifert is crap same thing with nitrate, 50 ppm I refuse to believe that

I don't believe that pH is accurate, but these aerations tests will help determine if it is, and why (if real).

The Aeration Test

Some of the possible causes of low pH listed above require an effort to diagnose. Problems 3 and 4 are quite common, and here is a way to distinguish them. Remove a cup of tank water and measure its pH. Then aerate it for an hour with an airstone using outside air. Its pH should rise if it is unusually low for the measured alkalinity (Figure 2). Then repeat the same experiment on a new cup of water using inside air. If its pH also rises, then the aquarium’s pH will rise simply with more aeration because it is only the aquarium that contains excess carbon dioxide. If the pH does not rise in the cup (or rises very little) when aerating with indoor air, then that air likely contains excess CO2, and more aeration with that same air will not solve the low pH problem (although aeration with fresher air should). Be careful implementing this test if the outside aeration test results in a large temperature change (more than 5°C or 10°F), because such changes alone impact pH measurements.

What is your Alk at?

Low pH can also be a product of low Alk.

7.7 but I prefer to not Change it because last time I used soda it became 13 dkh

Lie.
Forget PH.

Not doing a "special testing method" again, I assume?

No i stopped that thing a long time ago but sometimes my test shows random things but it's a 1 in 10 chance, like ammonia

Ok, check the labels on the powders or whatever to make sure you haven't mixed stuff up. Test kits don't tend to give random results, it's normally the operator being random, lol.
