Nerite Snail pH: Ideal Water pH & Hardness
Ideal pH 7-8.5 · Hardness 6-20 dGH
The Nerite Snail prefers neutral water: pH 7-8.5 at 6-20 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.
