When I test my PH with the API Master Test kit, it says, my
pH is between 6.6 and 6.8 which is where I want it for CRS.

When I test it with a API strip, it says my PH is 6. 2.

When I test it with easy strips, it say my PH is 6.6

When I test it with my brand new PH meter, that I just
calibrated yesterday. The meter says, my PH is 7.4?

I am not sure what my PH is, and I want it to be around
the 6.6 to 6.8 area for Crystal Red Shrimp.

I don't know what to do here?
Any suggestions? Thanks, Doc

find some one with a liquid kit and see what it says. strips go bad fast and if there are more than one test on the strip it likes to give bad readings cause chemicals bleed in the water on the strip. it could be your didnt calibrate the meter right. only way to know is to keep testing and see if you get the same reading or really close several times with different water. how old is your substrate could it be leaching?

I tried everything from strips, pens, to liquids. I find liquids are the best way to go it gives you the best reading everytime. Digital pens works but I notice if get $60-100 ones u always gotta calibrate it everytime. Strips are never accurate.

Yeah, I think the liquid is probably right. It is also closest to the strips. I recalibrated the meter, but I still get the same PH reading. The meter is brand new and expensive, but I am not sure about it at all. I follow the calibration instructions exactly, and did the calibration twice, but it still does bounce around a lot.

My substrate isn't very old at all. Two months, and the tank is clean, my CRS seem perfectly happy, and are exploring the tank. They seem to get more colorful by the day to me. So, if it all goes okay for the week, I guess the PH is okay.
