When new animals arrive, you must never release them directly into the tank. Many of you likely have experienced animals dying because this 'water acclimation' step was skipped.
The water in the transport bag and the water in your home aquarium may look transparent, but their composition is completely different. Not only temperature, but various parameters like pH (acidity/alkalinity), GH (general hardness), KH (carbonate hardness), specific gravity, and TDS (total dissolved solids) differ significantly. When these parameters change rapidly, the animals experience severe stress.
Particularly dangerous are 'pH shock' and 'osmotic shock.' If pH changes abruptly by 0.5 or more, fish can enter a shocked state and, in the worst case, die within hours. Shrimp are even more sensitive to minor changes, and even slight differences in pH and TDS can cause molting failure or sudden death.
Water acclimation is a process where 'being too cautious is just about right.' Taking time significantly reduces stress on the animals.

The simplest and most convenient method. Mainly used for hardy freshwater fish.
The floating method is specialized for temperature acclimation only, and is insufficient for adjusting pH and TDS. During summer, if direct sunlight hits the aquarium, the water in the bag may overheat, so use aquarium covers or sunshades. Also, it's recommended to secure the bag with clothespins to prevent it from tipping over while floating.

The most meticulous method, recommended widely from beginners to advanced aquarists. Using an air tube, aquarium water is dripped very slowly into a bucket, gradually matching the water parameters.
During dripping, the water in the bucket tends to cool down, so in winter, wrap the bucket with a towel or temporarily place a heater in it. Also, if the drip speed is too fast, the effectiveness decreases. The correct pace is one that feels 'a bit slow.'

A method that falls between the floating and drip methods, suitable for situations like 'I don't have drip method equipment on hand' or 'I want to balance effort and effectiveness.'
This method is not as precise as the drip method, but it acclimate pH and water parameters more effectively than the floating method. It's also easy to use when introducing large numbers of goldfish, tropical fish, or medaka.

Shrimp are several times more sensitive to water parameter changes than fish. Use the drip method as the standard and take at least 1 hour or more. If the animals swim around vigorously immediately after introduction (thrashing), this is a sign of pH shock. If the difference in TDS values is 50 or more, take especially slow and extra time.
The difference in specific gravity (salinity) is the main concern. If the specific gravity difference is 0.002 or more, we recommend a thorough drip method. Also, the water in the bag may contain pathogens, so never pour the bag water into the aquarium. After acclimation, corals are recommended to undergo dipping treatment with specialized solutions, and light acclimation (initially dimming the lights) is also necessary.
They are relatively hardy, but seasonal temperature variations can be significant. Be thorough with temperature acclimation during summer's high-temperature period and winter's low-temperature period. Ammonia may build up from waste during transport, so allocate at least 20-30 minutes for acclimation.
For aquatic plants, 'treatment' is more important than water acclimation. Since snails and algae eggs may be attached, consider treating with dechlorinated water or specialized solutions. Temperature acclimation alone is sufficient for 5-10 minutes.

Br-Choku's breeders are careful with packaging and often provide water parameter information (pH, specific gravity, temperature, etc.) at the time of shipment. With this information, buyers can understand the difference from their home aquarium and choose the optimal acclimation method and duration.
Additionally, breeders are experts who have kept these animals long-term. One of Br-Choku's strengths is that it's easy to consult about detailed information such as 'what acclimation method suits this individual' and 'how long does transportation take.'
The first step in protecting animal life begins with proper water acclimation. Without rushing, carefully, and at the animal's pace, proper introduction leads to successful long-term care. If you have any concerns, please take advantage of Br-Choku, where you can directly ask breeders your questions.
