Thanks Jason. Man, it seems like every time I have a question, you're always right there to help out. Much appreciated!
I'm not shocking (yet), we just finished filling the pool today and got the pump running. The water has a greenish hue, and I know we have iron in the fill water, so I want to rule out organics first. That way, I know exactly what I'm dealing with.
I've added one bottle of sequestrant (added a little each day and mixed it manually) and it hasn't turned brown yet, so if it is the iron, hopefully one more bottle will take care of it.
While I'm on the subject of iron (please move or split the topic if necessary), if the water has changed colors, the sequestrant will change it back, right? I know, another stupid question, but I don't think I've ever seen that actually said anywhere.
