I have read a LOT lately. One of the suggestions was to lower the ph and shock the pool which would take the iron out of the solution, make it solid and allow it to settle, then filter and vacuum. Which I would have no issue doing now as the pool is not open yet. The other suggestions were to have new water trucked in or continually use a sequestering agent. The issue to me about the sequestering agent is the need to continually check for iron. If I am adding chlorine and the agent is wearing off won't it just turn brown anyhow? Having new water won't do any good for me. There are only 2 companies near me that would deliver pool water to my address, and apparently the one I used had some iron in their water. I suspect the other will be the same as they probably fill up at the same source. I'm just looking to do the BBB method and use as few unneeded chemicals as possible. I am also wondering if the pool store is just feeding me a load of Crud about the iron to continually sell me $16 bottles of sequestering agent.
