Ph Tester, Digital or Solution? Options

[a320]

Hi Everyone,

My first post. Would like to know what is consensus on ph testers? Do most people use digital or solution?

I'm currently using a milwaukee ph test pen for my aquarium tank (no green water) but it doesn't seem to instill
confidence as i think my buffer solution is not accurate at all. What sort of calibration buffers do you all use? I'm not from singapore so a headache sourcing calibration solutions here.

I've used the Ph test kits before and thought that a test pen is better....but having my doubts now as i'm not sure of the accuracy.

Could appreciate if anyone could share their thoughts......and also if possible some test pens/ kits recommendations, where to get them from and the price.

Thanks.

Hmmm........i was told by my local LFS to aim to get the PH to 7.5. That seems to be what everyone is trying to achieve. I'm just slightly puzzled why with all these coral chips for my 750litres tank, that the PH just stuck at 7.2. I haven't tried to recalibrate my test pen yet using the BS solution of 8.4 but cany anyone tell me if i should just leave it at 7.2 if my test pen is correct or aim to push it higher? If higher......is BS the only way?

Thanks
