PH pen broke.

Hi guys, my PH pen is stuck at 1 so I went out and got some pool testers made by aquacheck.

only problem is I couldn't see the back of the bottle in its package so I didnt see the test range starts at Ph 6.2.

Does anyone know what these test strips use so I can find the correct colour guide.

thanks..

id buy another pen.

buy twice

I've been using this liquid test kit for a while and it's reliable and easy.

General Hydroponics pH Test Kit - Plantlighting Hydroponics

The colors are easy to discern too, unlike most liquid test or strips. Using 3 drops per test I'll probably have this same small bottle for a long long time.

Milwaukee makes good stuff.. ask Earl.
