Thank yall so much for the quick replies. No, BigDave on the up grade cartridges yet. And I am having to replace these cheap suckers about every 3-5 days. Was waiting for refund and now going to order the unicel since had such bad luck trying to get the Filbur. Did get the skimmer in and ended up also putting a stocking in it to hopefully help catch as much stuff before it goes to the filter. Got a better vacuum which, discovered while vacuuming so much stuff was just shooting back into the pool as it cycled through the filter. Now Until I improve filter I'm using my broom and sweeping everything in a pile, letting settle again then siphoning out. Luckily so far have been keeping my chem levels pretty good. Still have pH 7.5-7.8 but, pretty stable. Hoping to see big improvement then with the filters. And yes, I'm remembering to enjoy the pool. Kids and grandson, Too. I guess I'll update when I get the new filters in. Thanks again Watermom, BigDave, Pappy, and PoolDoc.
