PH Monitor Suggestions

[whatcaneyedo]

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
