I am getting ready to install a SWCG system. I have read in various places that sacrificial anodes are the first best way to help cut down on metal corrsion in regards to pool parts. Today, I went to two local popular pool stores and neither had heard of Anodes. When explained, one store manager told me that an anode would put more metal in the pool and stain the liner and everything else. She told me this after admitted she had never heard of an anode before. While I am sure it has been addressed on this site before, I seem to be having trouble trying to search the threads.

So my questions are A) is it worth it to have an inline anode? B) Do ladders need separate anodes attached to them when an inline anode is used? C) Does the anode add metals that need to be removed? If how do you remove them? D) Should I even consider using an anode?

Thanks folks for your replies.
