55 Gallon Tank %100 water change, and .15 ammonia?!

[SomeoneFISHy]

Hello! I did a %100 water change (tank was filthy, gravel needed cleaned) and we got the water filtered, and filled with salt to the appropriate SG. I did a test, and the levels were .15. Why?

Test your water right out of the tap. Just fill a glass and test it, for accurate ph test have to let it sit for 24 hours. Ammonia you can test right away. Its likely the ammonia is present from the tap.. If your going to be running a saltwater tank you will likely have to invest in an RODI unit. The minerals from tap water will likely cause you several headaches and issues down the road.
