Anyone Encounter This?

I age my water for my shrimp tanks with water been pre-filtered by 3 stage tap filters. Then water also treated with a dose of Seachem Safe. Age water tank got a flow of raw bubble as aeration.

Did a ph check on the water in the whole farm and might as well test my age water tank one as well. Shock to find my PH level is 4? Thought PH tester spoil or not calibrated properly so test with a few test kits still the same. And tap water is 8.4 here. Didn't know my age water so power.

Till now still dunno what causes the PH in the age water tank to drop so dramatically....

Bro that seems to be the case lately. Many complaints of low ph in AQ.

Hmm... Because there's alot of age water tanks in the farm. Only different is that they never go through the tap filters and not using the same water conditioner as mine. But the different is huge when it comes to the readings compared to mine.

My raw tap pH readings had gone from 7.8 to 6.5. Seeing as how an acidic pH means that the buffering is also almost gone, I'm not surprised that it only takes abit of additives and filtering to drop it more.
However, bubbling the thing should drive away CO2 and increase the pH slightly...not sure why it's plunged so far to 4.

Could it be that the source of the water supply (PUB) has some problem?
