Testing your Pond Water

If you haven't tested your Pond Water yet, now would be a great time.

Check you pH level. The best time to test your pH is early in the morning.
This will give you a more accurate reading.
If your pH isn't neutral now is the time to start trying to balance it out.
Changing your pH level is a slow process and getting started now would be beneficial to you later.

Check your Ammonia & Nitrite levels. Ideally you would want these to be zero.
High levels of Ammonia and Nitrites can be harmful to you Pond Fish.

You can also check your Chlorine/Chloramine level, Phosphate level,
and Salt content of your Pond Water to be on the safe side.

Testing your Pond Water for any potential problems now will help you out in the long run.
The earlier on you take care of these problems the less work you will have later on during the season.
