    Underlayment or concrete pad or flashing or .....

    Have a 28' above ground pool. We are having some trouble with the ground underneath being very soft it seems and getting lots of wrinkles, holes, dips, etc in the liner. Causing lots of work and upkeep in trying to keep it clean as nothing seems to get the dirt out of the little pockets and...

    Pressure differential - potential issue?

    The water is still a little cloudy, still getting the water chemistry dialed in with SLAM, had 0 CYA so had to wait to get that delivered and get added. I am definitely sucking up a lot of stuff when vacuuming, I just felt like only two minutes of vacuuming wasn't much and worried I was...

    Pressure differential - potential issue?

    I have a Pentair Optiflow 1HP pump with a Sparco hi-rate sand filter on a 28' above ground doughboy. I have noticed lately I am having a hard time keeping a prime on the pump especially when vacuuming. I can only vacuum for about 2-3 minutes and the pump loses its prime and most all suction...

    Time for sand change?

    So having not had a pool like this before, what is "clear" or what should I expect? I should see the floor on the far side of the pool standing from the edge, as in 100% crystal clear? Just not sure what to expect :)

    Time for sand change?

    Ignore the question on the vaccuum, I found a manual online (previous owner hadn't left) and I have a better idea of how this is intended to work.

    Time for sand change?

    Woohoo, I couldn't even wait to post, but I have (preliminary) passed the OCLT. Had the same FC at 16.5 this morning at 7am as we had at 10:15pm last night, with a CC of 0.5. The water is mostly clear (standing at the edge I can see the bottom halfway across this morning). Not sure what I...

    Time for sand change?

    Ok, I assumed that was the answer on the CYA. 38 was relative in the sense that it was a touch over the 40 line, but well below the 30 on the cylinder. The other reading I had was "32" in the sense that it was a touch below the 30 line but well above the 40 line. So I was inferring the value...

    Time for sand change?

    Asking this, presuming I know the answer already.... Can CYA go up without the addition of any stabilizer? Originally I was getting readings around 30 (4 days ago), and now we are getting a reading of 38 as of last night. Or can CYA readings on the TF100 kit be skewed based on the water...

    Time for sand change?

    Haha thanks @Griswald. Touche. So I received the TF100 test kit and started my first round of true battle with the pool. We already had cleared up most of the green with "pool store" suggestions and way too much $$$ spent. But here we are. First round of testing at 6:55pm (before adding...

    Time for sand change?

    Thanks for the reply! I am seeing more and more in not going back to the pool store. I have done quite a bit of reading on here which was what led me to start doing liquid bleach instead of the crazy expensive bags we were doing.... I am ordering the test kit and things now. The other thing...

    Time for sand change?

    Hello, First time pool owner, just bought a new house that has a 28' Doughboy aboveground vinyl pool. Pump wasn't working for about a week (clogged?) and the water from nice sparkling clear to swamp water. We used a local pool shop and added over $350 worth of chemicals over about a two week...
