PH Monitor Suggestions

[linz8392]

Just wondering what digital PH Monitor everyone would recommend.

I'm looking at some on ebay but not sure what to get.

Are any more accurate than others? What's your experience?

thanks

You could buy a basic and almost useless pH monitor for close to $100. Or for a little bit more you could get an all in one aquarium controller with pH monitoring/controlling capabilities. Neptune, Profilux, Reefkeeper etc.

+1, a basic controller can be expanded to control temp., redox, lighting,etc.

i have a millwalki that i never use-constantly have to keep on cleaning the tip and recalibrating.i find it is easier and cheaper to use a test kit
