Target guidance:
Marine/Reef: typically ~7.9–8.3 (stable daily swing).
Freshwater (community/planted): often ~6.5–7.6 depending on livestock and CO₂.
Best Practices
-
Test at the same time daily to observe natural swings.
-
For reefs, check near lights-on and lights-off to understand diurnal changes.
-
If using CO₂ in planted tanks, test before and during the photoperiod.
-
Adjust alkalinity (marine) or KH/buffering (freshwater) before chasing pH.
-
Log results; re-test after water changes or dosing.
