Acclimation

Tanım

The gradual process of adjusting new fish to the temperature, pH, and chemistry of their destination aquarium to minimize shock. Drip acclimation is the gentlest method.

Ayrıntılı Açıklama

Fish experience osmotic shock when moved between water parcels with different chemistry — cell volumes change as water moves across membranes. Drip acclimation (adding destination water at 2–4 drops per second to the shipping bag over 1–2 hours) gradually equilibrates chemistry while ammonia accumulates in the bag (shipping water pH often acidic, suppressing NH₃ toxicity — raising pH during accclimation releases toxic NH₃). Temperature matching (floating the bag 15 minutes) should precede chemical acclimation. For sensitive marine invertebrates (corals, shrimp), specific gravity and temperature must match within 0.001 and 1°C respectively. Freshwater fish are generally more tolerant of gradual chemical change than marine species.
