    Conversion Problem

    Hi,
    I'm new to this site and was converting my pool from Baquacil to the chlorine (bleach). but I've run into a problem, for some reason when I try to vacuum the pool all of the Baq goo at the bottom gets sent back into the pool from the filter. Iíll give you all the details I can now to help you guys out.

    Pool was brand new last year filled 2/3 with city water 1/3 well water with high rust content.
    We used Baquacil for the first year and closed the pool with Baquacil in the fall.
    Pool was great last year and I kept everything in spec. I wanted to switch to chlorine due to the cost of the Baq.
    When I opened the pool about a week ago the water was crystal clear all the algae and goo was pushed out of the water to the bottom it had a nice layer on it.
    I filled the pool up from the closing level with well water.
    Used the conversion tool to figure out the amount of beach to add and let the ďmagicĒ happen.
    There was for sure Baq still in the water it changed to a mutant orange color and had sludge floating on top.
    I had to backwash about every 30 minutes for the first couple of hours.
    I started this on the weekend so I kept checking hourly and adding beach to keep FC at 15
    So far Iíve used 25 128OZ of wal-mart beach at 7.86 CI vol.
    The colors have gone to a greenish blue and this morning after 3 days I could see the bottom.
    I attempted to vacuum but like I said all of the crud at the bottom was shooting out the filter I tried to backwash it and go again but nothing.
    The stuff at the bottom was thick it made the water in the pump housing look like orange juice, is it just too much at one time for the filter. Or is possible my filter sand has had it.
    This morningís specs.

    First thing thing to check - although unlikely - is that the multiport is set to something other than filter. That costs nothing and takes but a second. Then go on to the next step. The stuff is going through your sand filter. It could be that it's channeled. The cure for that is to open it up and probe around gently with a broomstick or something and break up any clods. If that doesn't help, then try adding a little DE to the filter. Be aware, it will likely load up really fast, so don't set it to filter and go to work. You'll need to be able to watch the filter pressure and the return flow and be ready to backwash a lot.

    Thanks for the tips, the port is set to filter so I'll get to work on opening up the filter and shifting the material around.

    Well there must not have been any channels in the sand I opened it and gave it a good stir the sand looks good to me there wasnít any clumps I just put the sand in before I opened the pool this year so it was brand new. Iím going to try the DE I think the stuff is just so fine the sand filter canít grab it. Itís like a orangish silt Iím guessing the remainder of the baq goo.

    The DE is working great, I was able to vac without anything coming back into the pool. I need to monitor my FC overnight now but I think I'm just about there.
