Welcome to our forum.
Although there are some knowledgeable people on this site, most people here don't even know what a "chelating agent" is. If someone doesn't truly understand spa chemicals, they have no business telling others how to take care of a spa. My advice to you is to "Ask Your Dealer".
A chelating agent whill pull the metals out. There used to be a belief that "chelation therapy" was a treatment for autism. Until it sent a small boy into cardiac arrest and he died, now I don't know if anyone practices that.
This is just my opinion, You have a dealer that probably helps over a thousand spa owners in your area balance their water. Most likely your dealer has at least 10 years of experience in dealing with the water in your area. Your dealer most likely understands the equipment in your spa. He (or she)probably understands the chemical kit that you were given inside and out. your dealer has probably been to several chemical schools, and understands chemistry better than 95% of the people on this site. Why wouldn't you ask your dealer?Although there are some knowledgeable people on this site, most people here don't even know what a "chelating agent" is.

My dealer has not a clue about chemicals. Why would you automatically assume that [glow]all[/glow] dealers can answer chemical questions? Believe me, 95% of the people on this site care more than any dealer about answering questions from other forum members.
