I have a 610g that I set up about 2 months ago. My water parimeters have been perfect exept PT of around 8.28 and 0,0,5-10 however my fish are acting strange, It could just be the large tank but I also have a drip system on this tank that I have never used before. are there any test for clorine that my not be getting removed by my carbon filter. or any adition test that I could due I so where would i get those test kits
