Will this cheapy pH meter work?

What would you suggest for a pH meter that won't break the bank account?

I have been using the yellow one for a year or two . Every so often check it with the ph calibration fluid.

PH is something that you need to worry about more in fresh than salt water.

Maintain you alk and oxygenationand this allbut takes care of itself.

Being honest if your PH is low but your alk is already right, what are you going to do apart from say oh shit?

I haven't measured my PH for over a year :eek

The pen you are looking at will give you a reasonable result - maybe just get it confirmed at your LFS every 6 months or so.

I measure it all the time , I use mine to check what PH reading I am getting out of my CR.
Just to make sure the probe in the reactor is right!

Sorry I did forget about people running calcium reactors, pretty important for those guys.

These pens are inaccurate, because they use a single calibration point.

They will be able to tell you if solution is 4, 8, 10, but when it comes to the decimal digits, they are inaccurate.

Depending on on application, it might be enough.

Check calcium levels for one....

Unless you get a dicey ph pen, they are all much the same, the workings are pretty simple. As someone else mentioned, just make sure you have some calibration fluid and check it occasionally. I paid about $7 for my ph pen from china, works fine.

Interestingly, in a few weeks I'll have access to a full blown, laboratory grade test kit. I'm looking after someone's tank and I'll take the opportunity to test its results against my pen.
