I purchased a 16 Foot Intex Round Pool with Salt water chlorinator. I am having a problem with the color of the water. The water had a green hue while i was filling it up from my hose. Everything is working fine with the pump and all. I had the water tested and they said it is perfect, chlorine level, salt, etc. I told them it is perfectly clear but it has a green hue to it and they told me to run the filter for a couple of days and keep cleaning the filter. I did it for 4 days and nothing. Does anyone have any ideas on what this is? I thougt it was iron and put in a metal out product but it clears it for a couple of days and then it comes back. Any help would be appreciated. Thanks.
