My water turns more green every time I add chlorine. My test actually turns bright pink then totally clear and then i ad about 5 drops reagent before it starts turning pink then it goes bright pink again and around 55 drops it starts clearing. Im reading that this is usually copper but maybe iron. I've had pool store test and they say I have 0 of each in pool. However I have stains that came off with vit c test. So do I need to get my own test kit for copper/iron? Does this sound like good plan? ... Drain as much water as I feel comfortable doing and then hit with blue and pink stuff. I bottle of each. OR. Do I try to determine if its iron or copper as main issue and treat for that metal type using 2 bottles of 1 metal type. If I drain 1/3 I'll be around 10k gallons. I was hoping there was a simple test I could do using household products to test for iron/copper

Other thought was should I even drain to treat? I figure at this point some fresh water won't hurt but might be cheaper and easier to buy more bottle of majic instead.
