Hello, I wanted to update. I have been using the bleach for a few days now. I received the HEDP. I have a question about it. The ChemTek HEDP says that it is a "clarifier." I have been using SeaKlear Clarifier for the past two years, and I really like it. The SeaKlear also says that it removes metals from the pool. Can I use the SeaKlear regularly to help remove metals from the pool (in conjunction with the Culator)? I received the ChemTek HEDP online, and I can get SeaKlear closer to home.

Also, SeaKlear makes a citric acid based stain remover. Is this something I can consider using to remove the stain on the steps and pool liner?

Thank you!
