Hey all,

Just wondering - how good are digital ph testers? I figure they should be easier and more accurate shouldn't they? I'm looking at one that is quoted a 0.1ph error max which is better then most manual ones

Easier, yea, and probably more accurate because you're not trying to compare colors by eye, which can be hard when the solution color falls between the colors on the card. But unless you have fluctuating pH problems, or a LOT of tanks to test, the almost-right guesstimate you get from the liquid tests should probably suffice.

Thanks for the info - I might end up getting one; they're not really all that expensive (only about $30AUD) which you can pay close to for a good manual testing kit. The one I'm looking at takes the temp too which would be handy for refilling tanks.

For that cheap, yea, its worth it. I thought they were a lot more expensive than that.

Hmm.. interesting. I like it, although I must admit that I've gotten lazy about testing for pH.

I looked at some online sites, and the digital pH tester is about $90 US, so $30 AUD is a great price.
