Has anybody use these pH digital testers? If so, would you recommend over the API pH chemical test?
I've had one for a couple weeks and it seems to work great. In the long run it's much cheaper and more convenient. Actually the exact one that is pictured there.
How often are you actually going to use it? I mean I haven't tested my PH (or any other water parameter that matter)for years.
I test my pH a few times a week, guess you could say I'm a bit OCD when it comes to my water parameters.
And does it ever change?
