Has anyone had any experience with AmQuel causing acidic water. I had been treating my 30 gallon with Amquel while it finished cycling. Tank has been running for at least 8 weeks. I know have 4 tiger barbs in it, reading 0 ammonia and 0 nitrites about 40ppm nitrates after doing a 15% water change. I had dosed this tank with AmQuel to protect the barbs against an ammonia and nitrite spike several times without doing a water change, Would this cause acidic water? This is the only thing I can think of and my tap water is typically very alkaline. I did a 40% water change and the parameters came out normal I also moved my bristlenose pleco in there that was taking up home in my ten gallon as he is getting kind of big and rambunctious and very competitive with my oto cats for food.
