How to Test your Pond Water
Hi, I am Patti the garden girl and today we are going to check the pH level of my pond here. It has been sitting for a few weeks and I just want to see where we are at.

I have here a fresh water test kit and it comes complete with a bunch of different tests. Right now I do not have any fish in here so what I want to do is I want to test just the Ph to see whether it is more alkaline or more acidic.

Okay, here is the key pH indicator solution, now what I have to do is I got to take this and now I am going to put three drops. Now, I got to cap it and then just shake it like this. That is already giving me a very, very blue reading, we are going to check this little color card and I am going to say that we are at 7.6.

The next thing we are going to do then since we got the highest reading is the high range indicator solution. This one I am going to put five drops. Now I am going to take my little color card here and put these together. Now, I think that is reading between a 7.4 and a 7.8 roughly.

Now what that exactly means is that my water is more alkaline than it is neutral of than it is acidic. This range right now is a great range for a lot of different types of fresh water fish.

I hope you all will go out and get your own kit and start testing your water, it is a great thing to do with children. I am sure you will be really surprise in how smart your kids actually are if you do get them to do this test with you. I am Patti Moreno the garden girl. Thanks for watching.
