can i add stresscoat straight into my tank. i forgot to put my dechlor in yesterday during the water change . would i be okay adding it now < it being stresscoat obv. >
If you've only made a small water change, and your city's water isn't laced with high amounts of chlorine, you'll get away with it. Not something i would do regularly though.
And yeah, like Tolak said, if its chloramine, you'd better add it in.
