    SLAM going on FOREVER

    Hello all -- I've been a member for several years, and had good success, but I'm really struggling to get my pool open this year. I have been in SLAM mode for two weeks as of today, and while I'm seeing progress, my rate of improvement is so slow that I'm afraid it's going to be time to close...

    Perhaps a cornerstone element of Trouble Free Pool Care (TFPC) is understanding the relationship between the chlorine in your pool and the stabilizer you put...

    Preparing to SLAM

    Moved from here. I'd like to piggyback here, as I'm about to start a SLAM myself. I'm trying to get rid of 2 tiny spots of black algae (both less than dime size), one small spot of green algae (less than a quarter), and the remnants of mustard algae (this was kind of bad, and I shocked it...

    I’m a fairly new pool owner.. bought this house with a pool about 2 years ago and have had nothing but problems with keeping it up. I even had to drain it completely last year and refill. I think one of the main problems is just age.. the house is about 20 years old and I’m thinking the pool...

    SLAM Interrupted

    SLAM question for the experts... I was a little lax in my pool care leading up to our summer here in Phoenix and got home last week from a work trip and had some green. I SLAM’d Saturday and Sunday, the pool was crystal but I am honestly a little unsure on my OFCLT. The lighting can be tricky...

    Need to SLAM, rain coming

    A couple questions please? I need to perform a SLAM on my pool. I understand liquid chlorine is best to use, but is liquid bleach the same thing? And/or used in same quantities? Also there is rain in our forecast. Possible today, clear tomorrow, then two days of rough weather. Is it a waste of...

    SLAMing your pool is the best way to eliminate algae, sanitize your pool and get your water crystal clear. If you have algae, or the CC level is above 0.5, o...

    MA slam for weeks, Mustard Algae will not die

    I have tried everything. Regular SLAM then MA SLAM. For weeks now. Wore out the steel brush. Pump on 24/7. Tried applying bleach directly on to the algae areas with a 10’ plumbing pipe (a trick a pool guy showed me once). Nothing works. Passing OCLT but the mustard is still there. Walls and...

    NO CYA

    Hello Forum! I opened my pool Monday and it was greener than previous years. So I began my SLAM. I SLAM'D it based on my reading from the end of the year for CYA levels, which were around 30. So I SLAM'd at about 16 for FC. However, I tested my CYA levels and it's reading zero. The pool is...

    Slamming with SWG

    Hi Guys! Quick question, I have read that when slamming it is not needed to run the SWG. Which I don’t do...With that being said my CYA is 40. Should I slam with a CYA of 40 pass the OCLT then add stabilizer before running SWG. Or should I add stabilizer during the slam so when I pass the OCLT...

    SLAMing inground pool with DE filter, no recirculate...

    This is my first time opening a pool. I think I closed down too early last fall and therefore opened up my pool to a nice shade of dark green. Never fear! I am a true believer in the TFP SLAM method and have stocked up on liquid chlorine. I went through my first day, lots of sweeping and...

    0% Chlorine all summer

    So last year I became a new pool owner and before I found this site, I added about 6 bags of cal hypo to my pool to shock it and ran the filter for a few days non-stop. The cal-hypo of course raised my CH but kept it within safe range. Once I found this site, I tried to apply the slam process...

    Chemistry Tests Look a SLAM required?

    We had our IG pool resurfaced in December and chemistry was balanced immediately after by our pool guy. I took over maintenance after a few weeks and was simply brushing, vacuuming, monitoring chlorine and pH levels until a couple of weeks ago. We had zero CYA because of the new water, so I...

    Slam Question re CYA and Chlorine Addition

    Starting up and we need to SLAM. Our CYA is 0. So two questions for guidance: 1. To raise the CYA is there a top limit of how much of the Clorox CYA to add at one time - or use the entire amount of CYA as recommended on the label for the water volume of the pool. 2. Can I add a limited...

    Muddy pool SLAM cleanup

    Southern California had a lot of rain this year and a few weeks ago our bank had way too much overnight and mud ran down our slide steps and into the pool. We woke up to a very brown pool. We never had this problem the year before so looks like it’s only an issue with large amounts of rain. We...
