What exactly was done after the build? Have you discussed this with your builder? Give us a timeline of what was done. How did you treat the water/what did you add to the water? Post a full set of test results to include: FC CC pH TA CH CYA Tell us all about the pool......and equipment...

Hi oshpappy :wave: Here's a link to our Pool School article for closing/winterizing your above ground pool: http://www.troublefreepool.com/content/145-closing-winterizing-your-above-group-pool Let us know if you have questions.

I suggest that you let the FC drop <10 and adjust the pH back up into the low 7's ASAP. Then resume SLAM.

Yes it is. :cry: :cry:

Backwash when the pressure rises 25% over clean filter psi.

:smile: "Not bad." Indeed! :goodjob:

Good to hear things are looking better. The OTO (yellow drop test) will test for the presence of chlorine from zero to 5, not 50. Ignore the BRomine side, you have a chlorine pool. The FAS/DPD test (which is included with the recommended test kits) will test FC up to 50! Wait until all...

If you don't have one of the recommended test kits, you need one. The TF100 is the fav around here. Link in my sig. We don't trust test strips at all. If the CYA/stabilizer is 30, then you need to maintain FC between 2 and 6 and never below 2. After you get the metals issue resolved, you...

You got it :goodjob:

okay, thanks. It would help to have your location & signature, as kiss4afrog mentioned. Go to and select "settings" top right under Pool School button. Then scroll down (left side) to 'edit profile' and then 'edit sig'. What test kit are you using? We need to see: FC CC TA CYA CH If you...

^^ Check around Please answer the three questions in my other post. :wink: whoa! I hope we can avoid an AA treatment in the future by sequestering the metals and avoiding stains :smile:

Exactly what did you add and how much? Did you add CYA separately? For now I suggest that you: 1. lower pH to about 7.2 wait about half an hour/retest/confirm and then 2. add about 2 or 3 ppm chlorine in the form of bleach/liquid chlorine (use PoolMath to calculate dose) Wait about half...

Welcome to TFP :wave: Please post a full set of test results and let us know how you got them. - - - Updated - - - The next to the last paragraph in this article shows the sequestrants we recommend: http://www.troublefreepool.com/content/137-metals-in-the-water-and-metal-stains

Showoff! :mrgreen: heh heh Good job :goodjob:

66 degrees :shock: Going to get a sweater after reading that :mrgreen:

^^^ what Jeff said :wink: How does your water look?

Right, and we would also like to see some pics along the way :p

^^^ yep, what Dave said^^^ Make sure to send pics to them, too!:D

You should have warned us and I would have put on my sunglasses before looking! :mrgreen: Nice work! :goodjob:

Make sure you follow instructions from the builder because you do not want to do anything to void a warranty. Your primary concern is keeping the pH in the 7's. You are going to need a lot of muriatic acid. Test daily and adjust pH as often as needed. The easiest way to add FC and CYA to new...

Bump :bump:

I suggest you use the sock method for adding the CYA.

Pls post a full set of test results and let us know how you got them :testresults: WE need: FC CC pH TA CH CYA

Yeah, go ahead and use your tabs. Keep track of how many you use and how much CYA is added.

You should backwash when the pressure rises about 20 to 25% above starting/clean filter psi.

You might want to also try a deep cleaning on the filter: my-sand-is-channeled-how-to-fix-it-t7626.html BTW, what size sand filter is it?

You can try adding some DE and stick a round to keep an eye on the pressure: pool-school/add_de_to_a_sand_filter

Welcome to the forum :wave: We have a member that has rehabbed a pool similar to yours, with pics :) my-pool-refurb-paint-is-complete-t7086.html

What kind of sock are you using? But, the sock should be a couple of knee highs (doubled up is my preference) or old cotton socks (no holes). The sock should be hanging in front of a return to keep it agitated. As Bo said, giving it an occassional squeeze will help, too. If you use this...
