Okay so I was giving my GT's tank a water change today and when I do a water change I usually use milk gallons (I've got a whole collection of the ones I've saved up over the years). But today I filled one up thinking it was one of the ones I usually used but instead it was one my parents had just finished and I didnt realize this until I started pouring the water into my tank and it came out with a milky haze. Is the milk going to do anything to my fish? I sure dont want my GT to die or my Texas.
