Guppy water parameters & overlap
Use this freshwater pH, GH, and KH overlap tool to avoid aquarium temperature mismatch and water hardness conflicts before choosing community tank mates.
Temperature72-82F
pH7-8.2
GH8-20 dGH
KH4-12 dKH
Stability notes
Use these ranges as a compatibility window, not as a reason to chase an exact pH number. Stable temperature, mature filtration, and gradual acclimation are safer than frequent chemical swings.
