Hello, I recently purchases an 18 foot Intex metal frame round pool. I have been following the super simple chemistry recipe that includes the use of bleach until the dichlor from amazon comes in. This is the 3rd full day of the pool being filled with water. It seems that the pool water has a green tinge to it. I am not sure why this is, as I am following the recipe exactly as it says and it has only been 3 days since I have filled it. Any ideas as to what is going wrong and how i can fix it?
