Rummynose Tetra pH: Ideal Water pH & Hardness
Ideal pH 5.5-7 · Hardness 2-8 dGH
The Rummynose Tetra prefers soft, slightly acidic water: pH 5.5-7 at 2-8 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.
