    New Pool well water Sand Filter Problems

    New and Filled 2 weeks ago Northern Indiana Well Water
    Vinyl Pool
    33,000 Gal
    Pentair VS 3HP pump 220v
    Pentair 125k Heat Pump
    Pentair 60D sand Filter

    I knew iron was going to be a problem
    However, this sand filter from my thoughts is trash.
    I've been filtering over the past 2 week none stop and the water still isn't clear
    Yes I can see the bottom drains, but overall I'd expect much more clarity.
    I'm so fed up I have just placed a new order

    Pentair Quad 100sq
    I still have time to modify this order.

    What are your thoughts?
    Anyone currently with this filter?
    Should I just go with the DE instead of the hybrid?

    Furthermore, I'll be plumbing this myself for a variety of reasons.
    Should I go with the multi or just straight through like a cartridge filter to increase efficiency.

    Will I truly see the results i'm expecting from this filter?
    I have no problem with the added maintenance if you water becomes and stays immaculate.

    Any thoughts would be greatly appreciated this is my first pool and I've done a decent amount of homework

    I appreciate the insight,and lastly I have a 2 week old sand filter FOR SALE

    THANK YOU

    Welcome to the forum.

    Filters will not remove iron from your pool....were you expecting that?

    Iron laden water must be treated with a sequestrant to keep the iron in solution
    Will I truly see the results i'm expecting from this filter?
    Tell us more about what you are expecting and what your water currently looks like. A pic would be helpful. I will also say that most water clarity issues have to do with water chemistry.....not filtration shortcomings.

    I am afraid another filter will give you the same results unless you get to the source of your problem.

    Cancel that order. Most clarity issues are usually chemistry issues. Duraleigh said the rest.

    I was under the assumption that DE filter to a much smaller micron better able to clear up you pool.
    I'd like to use minimal if any chemicals in this pool why I was leaning toward the Pentair Quad.
    Does everyone here use sand filters?

    From what I can tell all the iron is currently in a solution form.
    The deeper end of the pool looks more rusty because you're looking through more layers of iron solution of water.
    I could be way off on this but this is was I can tell.
    I've put vitamin C in a sock and scrubbed the deep and with no prevail. Which lead me to believe the iron is not staining.


    I've used 40,000 gal worth of Metal Free Leslies
    The pool builder also put in 20,000 worth of a stain and scale when I filled up the pool

    You have several misconceptions about pool water management but let's start on this one first. You must sanitize your pool and keep your pool free of algae with chlorine. Are you putting chlorine in the pool now?

    I would Read "The ABC's of Pool Water Chemistry" up in Pool School. That'll give you some basic info on the necessity to have chemistry in your pool.......you cannot manage your pool without them. No filter will function unless you have correct chemistry.

    OK.

    1. What are you using to chlorinate?

    2. Did the last sequestrant you added clear the pool and then the green returned later?

    3. What is the TA of your fill water?
