pH problems

Hi, everyone!

I discovered that my substrate, Fluval Stratum, would lower pH after I got the dry start going and thought I could just raise it with CaribSea aragonite. I've had the aragonite (1 cup in mesh fabric bag) in the water since I flooded it 2 weeks ago. My pH is always 6.0!

I've been getting a reading of 7.2 in my betta's planted 3.5 gallon, so I'm pretty sure the test solution is okay. My water comes out of the tap at 7.4

5 gallon
co2 (Fluval 20g kit)
Fluval Stratum Substrate
pH reading at 6.0 (liquid test)
KH and GH at 0-50ppm
72 degrees


Thank you for any help!

Fluval will strip the water of kH over time, and thus lower pH. it will continue to do this until its "full" and can no longer strip the water.

It is meant to do that.

CO2 will also lower the pH of the water.

A pH of 6.0 is perfectly fine.

Thank you for the info! I knew the substrate would bring KH down, but I thought aragonite would bring it back up. Bummer.

I have the API test for pH and 6 is the lowest it will read. It could be lower than 6.0. I read that nitrifying bacteria can't survive at 6.0 or lower. Is that bullocks? I'll have a small bio load, but I would still like to cycle the tank.

I'd remove that aragonite immediately. It's just spending the soil and shortening its lifespan. These soils are designed to keep near 0dKH.

Then I learned a hard lesson about lazy research.
