I have a small brownish stain on my liner that I'm going to test to determine if it's organic or metal related. For the record I just passed an OCLT test so I'm pretty sure it's not just algae.
So, I understand I need to put a chlorine puck in my net and hover it over the stain for a few minutes. Then if that area clears up, it's organic, if not then metal.
Questions: So I see the what-to-do for metal, but if it's organic, what do you do to finish off the stain? Do I just move the puck around over the stain until all of it is clear? Also, is there a danger of messing up my liner if I touch the puck to it?
Thank you.
