    SLAM - How Long????

    CYA - 40ppm Current FC - 22ppm Current TC - 0PPM Water is clear. Chlorine loss overnight is ~5-6ppm Cartridge Filter System Plaster pool *My pool was in BAD shape. I normally would have drained it, but I decided to do the SLAM to kill everything in the pipes, filter, etc... I am on day 15 at...

    Water Treatment - What Now?

    First, I want to say that we are first time pool owners of a 10k gallon, vinyl, filter cartridge using, chlorine eating, in ground pool, which came with our home purchase last fall. I've added what I know in the about me portion. If I didn't do something correctly just let me know. Based upon...

    Another Green Monster has appeared in Boston -- Wife is ready to kill me!!

    Hi TFP! I'm new here - been lurking for a few months but now I need some help! First month of pool ownership was a breeze (May 1-June 1). I used the test strips (LOL) and had no issues. Water was clear and all was good in the world. Then, around June 1, we started seeing some sediment in the...

    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...

    Is it time to SLAM?

    Bought a house that came with a neglected above ground pool (no idea how long). We purchased a new sand filter, cleaned out debris, shocked and got it to cloudy blue over the course of about a week. It has now been cloudy for over a month & 1/2 and we can not get it clear. Since the original...

    First SLAM paused, light removal question

    SLAMed for two days, both nights failed OCLT within 4-6. Pool water has been and continues to be very clear. I am considering pausing the SLAM (after perusing others in forum with similar issues) to take apart the pool light, ladder, and the cartridge filter and see if there's any growth there...

    Newbie advice needed- VERY high CC

    Hello - I am new to pool care and I want to make sure the advice I was given is correct before adding 14 GALLONS of liquid Cl. Last night I followed the SLAM chart and added 3 gal of liquid. Today I took a sample to Leslies because i thought I was using my new Taylor K-2006 kit wrong when I got...

    Question on stabilizer before I slam

    Hey y'all! I've had a pool for a season, but our small town pool supply store just went out of business, so I found TFP and am attempting to maintain it myself this year. I got a Taylor testing kit and got some numbers. My FC was 1, CC was 5.5, PH was 8.4, TA was 130, CH was 180, CYA was 0...

    Relationship Between FC and CC

    TLDR; I started SLAM last night. ~80 CYA, started at 0.3 ppm Chlorine, 7.5 pH. Dumped 4 gallons of 10% bleach. After it was dark (about an hour after dumping) FC read 34 ppm, CC was 1 ppm. This morning before the sun was up, FC read 22 ppm, CC was 0.5ppm. What is going on here? My novice...

    Safe to use Robot during SLAM?

    As a first timer I am trying really hard not to screw anything up (really do long term damage) as I figure things out. I need to SLAM the pool (starting today!) and I was curious if I should use a manual vacuum or if I could use my robot vacuum to help with initial clean up to see where I...

    Might need to SLAM???

    Ok so still in my first summer as a pool owner and all was great until a couple weeks ago we had a week of rain and I noticed my chlorine levels dropping. I’ve got them back up but then back off to normalize my chlorine input and down goes FC. ? Here are my current numbers as of 5 min ago. I...

    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...

    Brand new pool, needs a SLAM

    Short story. The pool has been done for three weeks. The guy responsible for set up and maintenance disappeared and the pool builder is not very helpful. “We build pools, we are not chemists” We have yellow algae already, so I am ready to slam. I have read through the pool school book but have...

    Draining pool to reduce CYA, replacing water, then SLAMing

    Hi. My CYA is off-the-charts high, so I'm about to drain the pool, replace the water, and then start the SLAMing process. I have read the SLAM article. Just to confirm I understand the correct order of re-introducing the chemicals, I need to bring the pH up to 7.2 - 7.5 with the new water...

    My first official SLAM... the TFP way

    OK people, I'm about to do my first official SLAM after studying posts on this site. My pool levels are pretty on point for the most part but my phosphate level is at 500 which is why I feel like algae keeps coming back on the walls within 2 days of scrubbing, despite having high FC levels...
