Aquarium Advice FINatic
I am trying to ease my parameter testing . I just dont like the color matching charts. Anyhow, I purchased a pH meter(pen style). My new probe is way off from my liquid tests. I want to recalibrate and have a small amount of solutions(7.0&4.0). Do I mix a solution from these tiny bottles? -OR- Do I drop a couple drops on the probe?
I purchased this on ebay. Company technika, model PHPRO
Any help is appreciated as always
