    GLB Sequa Sol Ingredient Question?

    I would like to add a maintenance dose in the future to control iron, the only one that is locally available is GLB Sequa Sol, the others: Jacks Magic, Proteam Metal Magic, and BioGuard Pool Magnet Plus are not locally available.

    In this post:

    http://www.troublefreepool.com/diffe...nts-t7250.html

    GLB Sequa Sol was recommended as it states:

    "Sequa-sol by GLB uses phosphonic acid derivatives, most likely HEDP, just like the Jack's Magic products and Proteam's Metal Magic. I am looking at the MSDS for it as I type this. It does list sodium citrate but in the box above it says CAS Number: Not Established
    Chemical Family: Phosphate
    Chemical Formula: Proprietary Mixture
    The MSDS is not necessisaily the ingredient list. By stating it's a proprietary mixture they can get around what is actually in it but by saying the chemical family is phosphate then it means it's a phosphonate since that is the main group of phosphate based sequesterants and HEDP is the most common one used in pools. The phosphonate based ones are also the effective sequestarants.
    The Acrylamide-Acrylic Acid Copolymer is actually a polymeric clarifier. It's main purpose is to keep the water from clouding since sequesterants can cause the water to cloud if calcium levels are high."

    I found the MSDS for GLB's Sequa Sol here:

    But I see none of the the ingredients listed in the post except Sodium Citate/Citric Acid.

    The question, is this product still worth purchasing?

    I was lucky enough to find one 1/2 gallon bottle of Omni's no longer available "Stain and Scale control. MSDS at this url, which states it contains both HEDP and Phosphorous acid, but it was the store's last bottle. I will use this as stop gap measure.

    I wish I could answer your question, but I can't. All I can tell you is what NOT to use as described in this post. I wish that the manufacturers would just be clear about what is in their products and if they are using HEDP, then just say so since that's mostly what we want. My pool is now, weeks later after adding that ****, finally starting to behave normally in terms of daily chlorine demand.

    Thank you, I will not buy that.

    It looks like you had a lot of fun in "The Great Sequestarant Hunt".

    But great for us people who came after.
