    Weed/ant killer question

    Should I / Did you spray weed killer underneath your AGP? I am getting ready to spread out the pad so we are ready to put the liner in tomorrow and wondering if I should do that first? I have some bermuda grass that keeps spreading to the sand and several small ant hills ...

    Ant killer as well as a weed killer that will specifically kill nutgrass is recommended.

    Thanks! I'll do that ... I'm not sure if I specifically have nutgrass ... but I know that it kills the grass/weeds that we have =)

    Trust me, you don't want to even chance it. It will grow straight up through the pool floor. Guaranteed.

    ok - I'll make sure to read the label first ... Hubby knows someone who has a weed that grew through his liner!

    Nut grass killer is a special chemical. It would not hurt to spray for it. If the nursery has the spray, it grows where you live. Spend the $20 or whatever it is and spray away.

    Re: Weed/ant killer question

    I had to google what it was ... and we do have some of that on our property, but not in the pool area ... and since we have been doing this leveling for months and I haven't seen it then I think I am ok ... but I will make sure to go ahead and get some of that spray and watch for it coming to this area ... learn something new every day!!

    Nut grass can be exceedingly invasive and it can grow through just about anything, including pools.

    Re: Weed/ant killer question

    I had one more question ... Is there a way to test a sand filter before you fill the pool ... I have no reason to believe that the one that I have won't work - but it hasn't been run for 1.5 years ... I guess I need to figure out what kind it is also so I can put that information here.

    Re: Weed/ant killer question

    I do not have a sand filter but reading here I have learned sand does not "wear out", it only needs to be replaced if you are converting from non-chlorine to chlorine chemicals. As long as the filter doesn't leak and internals are not damaged, it should be fine.

    The sand may need to cleaned but the backwash process will help to do that.

    Re: Weed/ant killer question

    Here is the information on the filter and the pump ... I guess I need to figure out how quickly the water will cycle with this set up ... how often I need to run the pump ... and if it is sufficient

    (and what of this information I need to put in my signature!)

    Filter - Hayward sand filter
    1.4 sq ft filtration area
    25 GPM dssign flow rate
    35 GPM filter and backwash rate
    50 PSI max work pressure

    Pump -
    Sta-Rite
    3.4 HP
    3450 RPM
