Here r a few suggestion to help properly acclimate your fish and invertebrates, including shrimp and starfish, for PH, Specific Gravity and temperature.
1. upon receiving fish, take a random sampling of the PH from the fish bags. A recently calibrated portable PH meter is best.
2. Using saltwater this is isolated from your system , lower the PH of the saltwater that is to be used for acclimation to no higher than .5 points above the average from the test bags. Note white vingear works best to lower the PH.
3. Empty fish and water from the bags into acclimation buckets and slowly being to drip the low PH water into buckets. Rate should be no faster than a slow stream. Do this for no less than 30 minutes. Increase time if water is colder than normal, or if fish seem highly stressed. ( Airline tubing works best as a drip line. The goal of this step is to wash away any ammonia and get the fish acclimated to the new temperature.
4. During step 3, it helps to slowly remve a cup or two of water from the buckets every 5 - 10 minutes.
5. Afterno less than 30 minutes of low PH acclimation, begin to add normal PH water to the buckets at the same rate that the other water was being added. For this process you can use water straighrt from your system. We recommended that this process take no less than 30 minutes. As water is added, repeat step 4.
6. Remove fish from acclimation buckets and place in the tank with low light on ( dark is preferred ) for few hours and ten U can turn the bright light back on.
Hope this will help.
