    • Is API PROPER pH powder safe with invertebrates and plants?
    • API PROPER pH powder is safe with invertebrates, but the powders in API PROPER pH 6.5, 7.0, and 7.5 bind to some trace elements which are needed as nutrients by live plants. Therefore, we do not recommend using these API PROPER pH powders with live aquarium plants.
