    Need to drain pool, uncertain about plumbing setup

    I recently rented a home with a pool, and I’m responsible for maintaining it. When I got here the pool was crystal clear, but I had no concept of how to care for it. The landlord said he would have his handyman come teach me how to take care of it. I didn’t know the pool should be checked and...

    OCLT affected by cold air/warm water?

    FC: 15.5 CC: .5 CYA: 40 Ph: 8.0 TA: not recently measured I’ve been in SLAM mode for four days (Keeping FC 16-17ppm). The reason: The pool hadn’t been swam in for a week. Yellow/brown sediment on the bottom, but not the sides. I believe it was pollen (based on forum posts I read here). I...

    Slow growing green algae despite good numbers!

    Hi all, I have been fighting green algae accumulation and proper LSI balance in our pool all summer without success. Any help would be appreciated! The pool water is not green, but green algae is slowly growing on the pool sides despite good FC levels and slamming. I started in mid July...

    Again... more bleach?

    I have a SWG pool and my tests call for more bleach every few days. I am increasing the SWG percentage and am now up to 35%, which is high for me. The water is very clear. I need to add some stabilizer, but before that, I thought that I'd ask the pool brains, do I need to SLAM again? 93* every...

    Algae, followed the SLAM criteria, here's what I've done and measured (timline), still blue & cloudy

    Hi there TFP folks! Name's Matt, I'm a newbie (both here on the site and as a pool owner). I've lost faith in local pool store folks, they only appear to want to sell me chemicals (and lots of em!). I've been silently following the prescribed SLAM instructions on this site. I'm an engineer and...

    End SLAM, Overnight Test and Marble Dusting

    Background: At the beginning of June, I hired a pool company to marble dust our pool. At the time, they said they were three weeks out. So I figured I would leave the pool closed until they did the work. I was busy and figured (apparently incorrectly) that they would be blasting the surface...

    SLAMming with no CC, FC drops

    I’ve begun the slamming process and I just want to make sure I’m not crazy. I know zero CC is the ideal outcome so I ‘think’ I’m still on the right track. I added a bunch of chlorine last night, that brought FC from 0 to 8 this morning. Added more, FC went to 12 (this was at 7:20am ET). Each...

    Question regarding SLAM and continuous filtering

    As I understand it when you SLAM you load the pool and keep it loaded with chlorine while you run the filter continuously. My very green pool was just opened for the season and filter pump pressure goes up from 12 psi to 20 psi in just a few hours as the filter does its work. Is it safe to run...

    Need help with a SLAM

    I had success SLAMing my pool the first time I tried in 2017 with the help of TFP (I think my original post is still up) but this time I'm having a lot of issues and starting to lose hope. Long story short - in the summer of 2018 my pool motor and booster pump went out. As you can imagine the...

    Add CYA first or Vacuum/Chlorine?

    Hi Guys, I need to SLAM my pool as it is pretty dark and gross looking. PH - 7.4 TA - 80 CYA - Below 30 Now I know CYA needs to be at least at 30 before I SLAM but currently my jets will start to slow due to the algae in the pool. What I'm wondering is should I just start adding chlorine and...

    SLAM complete--what's next

    Hey everyone! Finished my SLAM yesterday, CC is holding steady at 0.5 (All of my numbers are below, as of this morning) and passed the OCLT. What is the next focus? Is it to increase the pH into a more "neutral" value? I know that I need to just sit and wait for the FC to drop a bit, but can...

    Slam 10 days and the water is still very cloudy

    First let me say I’m fighting a very high TA water source. 330ppm. We had some equipment failure in October and had to shut the pool down and couldn’t afford the equipment because of medical reasons. So at the beginning of May I started cleaning the pool. I have used a water hose vac and...

    FC not increasing - am I doing something wrong?

I offered to help and got the pump replaced without any issues however am really having a hard time starting...

    SLAM vs. the WEATHER

    Facts as of right now: 1. Pool was partially drained at closing last year as I was running the Pristine Blue system and want to change over to bleach/chlorine this season. 2. Pool is now ridiculously green due to poor cover removal...all the debris was dumped into my CLEAN water and turned...

    Is SLAM Process Complete?

    Hi. I'm new to pool ownership. We bought our house last summer and I kept up maintenance of the pool all summer long according to information I found on this site (thanks alot!). I decided to forgo the pool maintenance over the winter since we weren't using the pool and would just clean it up...

    Install SWCG during SLAM or wait?

    Hello everyone. I'm toward the end of a SLAM at the point where the water tests good, low FC loss overnight, but is still quite cloudy. We've had rain on and off the past few weeks so that sets me back a bit each time. I figure I have another 1-2 weeks of 24/7 filtration to get rid of the...

    SLAM with solar blanket on?

    Hello everyone. I started SLAMing my pea soup pool about two weeks ago. At the time my CYA was 20, which though low, was nice to not need as much chlorine, (especially since I've so far gone through about 25 gallons!) I have some trichlor tablets left over (enough in total to raise CYA by about...

    Reconciling Recommendations for SWG SLAMs

    I'm a new pool owner and have found everything here super useful for getting up to speed with my pool. I'm a little confused on the advice concerning SLAM with salt-water though. On the one hand, it is usually recommended here that the SWG be turned off for a SLAM as its contribution is very...

    I went through my first SLAM, and first Cartridge filter clean since the completion of my first pool Opening Mid July.

    SLAM valve settings

    Hi all, I haven't seen much other pool equipment, but I'd guess mine is typical in that you can direct water coming to the filter/pump through either the main drains or skimmer (to various degrees), and water returning to the pool can run out the wall jets or to the positive pressure vacuum...

    CYA on a SWG Pool during SLAM

    Hello Everyone. Long time member but mostly a reader. I am very late into the opening of my pool this year. I have a SWG pool and I got my CYA up to 30. I am wondering about the need to have it in the 70's now since my SWG is shutoff until I am done with the SLAM process. Is it necessary to...

    SLAM; Solar Cover

    New to pool care. I just started SLAM. I have a brand new, still in box, blue 8 year solar cover. Do I leave it off for the duration of SLAM or is it safe to put it on?
