My filter tests at 11 TDS right now. That's just about as good as mine gets due to my very low water pressure.

Finny thing. I just set up two tanks yesterday out of curiosity.

#1 One has substrate and water. No sponge filter, and no hob.

#2 One has substrate, water, and just an hob with new bag filter.

Both have been left to sit the night.

#1 measures 7.1ph

#2 measures 8.1ph

Weird, huh?

Next I'm going to run a sponge filter in the 7.1ph one and see if the ph changes.

Default Re: changing shrimp water with diff ph

Just to throw in a quick one on "Spring" water...

Months ago I bought a sealed gallon jug of it from the local Walmart. Checked the water's parameters, which turned out not much different than those from my tap. Even the tds were high. Turned out it was bottled in a town about 10 miles away from my apartment. (Checked the label)

I had the feeling that it was basically unfiltered tap water.

I went back to buying distilled.

It's not weird it's as expected

The HOB will eliminate CO2 from water hence the pH is higher than the one without any water surface agitation.

Once the surface and the water body starts to move the CO2 will be gassed out and the pH will rise.

Awesome as usual danielt! So the mystery is finally solved then. Basically it's the co2 in the tap that is being gassed off that makes my ph high. Am I understanding correctly?

Yes, the pH swing is more noticeable if you don't have kH. As CO2 in the atmosphere will dissolve in the water it will cause a pH drop, it doesn't necessarily mean it comes from the tap.
