I have a 10 gallon aquarium that has been cycled with filtered water. I don't have any filtered water at the moment. My aquarium is a little low and my ammonia is testing a little high. Would it do any harm for me to add a couple of gallons of tap water treated with Stress Coat?
No I dont think so then again it depends were you live. Were I ive we use tap water for all fish except for saltwater of course if you treat it with a water conditioner or a little salt it should be just fine oh and not regula salt tank salt hope this helped
