Just wondering what I should be testing for and how often I should test my pond? My pond is still filling up, it's about 50% full now. No real concerns but just trying to figure out what equipment I should purchase to properly maintain and keep records with? As of now I have purchased an API test kit and that's about it. Being in Texas I think water temp and DO seem like they will likely be concerns of mine in the future.

On a side note, how do you all measure water temperature and at what depths do you take the temperatures?
