Hello I have a well and there is metals in it about 4 weeks ago I put in 4 inches well water in my pool. Pool is about 14,000 gallons. I put metal out 3 different times and 1 pouch culator each time it pulls the metal out then it comes back. I know it reacts to the chlorine.This week Sunday night I put in the regular amount of chlorine Pool stayed blue. Monday night regular amount of chlorine pool stayed blue.Tuesday night regular amount of chlorine pool stayed blue. This morning Wednesday pool blue.turned on pump 3 hours later green. I can see rusty metal where my skimmer attaches to the wall of the pool. Do you think my problem is coming from the wall of the pool where it is rusty.
