A pond kit must have!!
This test kit is my #1 priority when testing pond water. Maintaining the Kh value is key to keeping ph level stable and ammonia level at zero. Enhances fish color and plant growth.

Unfortunately these aren't accurate. I'm not sure what happened as the api ones are usually okay but these were giving me incorrect readings. Possibly a bad batch? Double and triple checked with the nt labs liquid tests.
