Betta (male) pH: Ideal Water pH & Hardness
Ideal pH 6.5-7.5 · Hardness 3-15 dGH
The Betta (male) prefers neutral water: pH 6.5-7.5 at 3-15 dGH. Test your tap water first — many keepers match this range with no adjustment.
Stability beats a perfect number. Chasing pH with chemicals causes dangerous swings; if your water is close, leave it. To gently soften and lower pH use RO water, driftwood or peat; to raise it use crushed coral or aragonite.
