Before adding fish to the pond, it’s important to ensure that the water
is acceptable to the fish. Here's all you need to know about Pond
Miscellaneous.
Prepare Pond Water
Make sure the water in your pond is adjusted for fish before you put the
fish in. A pond that’s filled with tap water needs chlorine compounds
removers so the fish can survive. These need to be in the pond well before
the fish are added. Also, pH levels need to be between 6.5 and 8.4 in order
for the fish to survive.
The temperature of the pond is extremely important. Water that is too
cold can cause a fish’s immune system to shut down. Water that’s too hot can
kill a fish. Ideally, the pond should be 65 degrees Fahrenheit, but a
temperature between 62 degrees and 74 degrees is also acceptable.
Preparing Fish For The Pond
Don't bring your fish home from the store and just dump them in the
water. Wait at least 24 hours to make sure the pond water temperature is
acceptable and then, while keeping the fish in its bag, float it in the pond
water for at least 30 minutes so it can get used to the water. Fish should
be added slowly. Don't dump them in all at once. See how they adjust to the
pond and each other before adding more fish. Some experts recommend waiting
two weeks before adding fish to the pond to weed out any possibility of sick
fish being added to the pool.
