slam

I’ve got a 14,500 gallon fiberglass pool that is typically salt, but we’ve let to put the generator back on. We just took off the mesh safety cover two days ago and the pool was completely green as expected. I have the recommended testing kit recommended here and found the ph high, so I put...

Alright, I was hoping not to have to make this post… as I have tried to follow all of the recommendations closely, but here’s the story. I built a deck around my pool this spring and during the process the pump was unplugged to be moved and hard piped (for about 3.5 weeks). During that span I...

Hi, I’m helping my elderly neighbor who is really struggling with their pool (my guess is dementia is setting in). I started managing my own pool last year, but I’m still trying to perfect it. Anyhow, the pool is concrete and in-ground with pebble tech coating and jacuzzi variable speed pump and...

I have a 15,000 pool with a DE filter. I started the SLAM process one week ago because I was losing > 1 ppm of FC overnight - sometimes up to 3 ppm. I have followed the process pretty closely. My water is crystal clear, my CC is zero, and I'm not seeing any algae - alive or dead - in the pool...

Hi, our pool is constantly turning green. I have the impression if I turn around and don’t look at it for an hour, it turning green. The plaster pool is about 25,000 gallons, I have a new pentair variable speed pump, a sand filter and a WaterGuru chlorine and ph device. Sat, cya and alkalinity...

I recently did a 3 day SLAM. Last night I finally reached no chlorine loss. Yay! But, last night wrinkles showed up out of nowhere in the bottom of my shallow end. Did the SLAM process cause this? My goal according to the calculator was 20 for the duration of the slam. Will they correct...

We got a 24' above ground pool in June. I found TFP right away on my first search about the aqua smarte system. I immediately went to TFP method after reading and bought the app. Everything has been perfect, I have even had a few friends with pools asking me about how I was keeping my pool so...

I don't know if I'm dealing with algae or dirt or....? We live in the country, acres of dry weeds and dirt around us, 50yds from a 10ac dirt lot with cows and goats. The wind blows around here. Three weeks ago the sand filter housing began leaking at a seam. It took 6 days to get it replaced...

Hi guys. So, long story short I just finished locating and piecing together a Bestway 24x12. She’s all filled up and looking pretty good. Since I had issues with getting filter up and running for about a week, I think I accumulated the beginnings of some algae. Luckily it’s been dying and...

13,000 gallon pool SWG and using Hayward EC40 filter. Can’t get the algae under control. Chlorine is currently about 3-4 ppm and CYA is about 55. I know this is a bit high for CYA but initially I tried to SLAM it at 30 ppm but I couldn’t keep chlorine over night, and the sunlight has been...

A week ago I noticed a little bit of algae starting to grow in the corner of our tanning ledge. Then I noticed that my SWG at 100% was not keeping up with the chlorine demands and was constantly 2ppm or less. Once I brushed the algae off it hasn’t returned. Also CC has never been higher than 0.5...

Hi all! I've read all the instructions and think I'm psyching myself out but looking for confirmation. Our CC level is 1ppm and CYA is 60, which leads us to this point. I used the pool math app to determine I need 13 jugs of liquid chlorine, which I then doubled. Here comes my (probably...

18 foot above ground pool in coastal Mississippi Replaced sand with glass media 1 week ago. Backwashed until clear. I’ve been following TFP since last summer (only 1 year of owning pool so far so still newbie). Last year, I think we had mustard algae and it took me a long time to clear. This...

Pentair IC-60, 53,500 gallons VSP currently running 24 hours a day pushing about 60-80 gallons a minute. Sand filter. Heater on bypass. My SWG is currently set to 0%. I completed the SLAM process last night. My free chlorine level dropped less than one, combined chlorine less than .5 and my...

We have been having hot weather (for us), 100F. Floating pool thermometer shows 79-80 at top 6" Pool has been crystal clear since spring. Chemistry was easy to dial in after winter and has been pretty stable through weekly tests. Today's readings using TFTestkit (2024 reagents) CL 10ppm...

Hi everyone! I need to SLAM my pool based on what I’m reading; cloudy, algea, and was green. But I’m having a hard time finding a 2006C kit. I see a 2006 on Amazon, what’s the difference? Could it still be useful? I’m in Toronto if anyone knows where I can purchase the recommended kit. I’ll...

Hello! I’m taking over pool duties for my parents and I’m clueless. We’re in Toronto so I can’t buy the testers from the links provided. Any suggestions? I’m hoping to get it by Monday so I can’t start working on the pool. It’s dark and cloudy. So far I’ve only been adding liquid chlorine and...

I'm in the process of my SLAM, my CYA was around 70 when I started so was doing my SLAM based off of that. Fast forward to 4 days in and I go to measure CYA today and it is coming up as 0. I did a bench test with a gallon of water and measured out a miniscule amount of CYA to mix in at the...

Left for a work trip with perfect water, came back 5 days later to a frog pond. Turn out a weir door broke and got stuck in the closed position and was blowing air through my system enough to shut off my SWG. Read up on the SLAM process and bought a ton of 10% liquid chlorine. I am waiting on a...

Hi! First time poster. Last spring/summer we were caring for a terminally ill dog in a wheelchair and did not end up opening our pool at all, so it was closed for 2 years. The winter cover shredded in places, and we opened the pool a month ago to a brown, smelly swamp. Went through 30 bottles...

We had an issue with high CC (above 2), so we began the SLAM process Monday morning using FAS-DPD test. We have gotten the CC under control, but our FC has only gotten above 1 on one test. We are adding 60-70 ounces of 12.5% liquid chlorine every few hours based on Pool Math calculations and...

Hi all! I bought a house with a pool in April. It had not been opened for the year, and we've been working on that for 3 weeks now. I've taken TFP as law and purchased the test kit and chemicals suggested. With the water green as can be, I'm trying to start a SLAM. My problem is that the CYA...

Started with an essentially black pool Saturday- lots of leaves, organic debris. Got it all out and started the SLAM process. Just want to make sure I’m on the right track. I’ve been maintaining SLAM via the CYA/Cl chart. Unfortunately my CYA is on the higher end due to adding too much...

Hi all, I'm a bit confused and could use some guidance. The app is telling me to SLAM my pool, but it's clear and I can see the bottom. Recently, after adding some pH reducer and shock (cal hypo), my pool became cloudy from being crystal clear just moments before. The FC shot up to 11 PPM and...

Hello, new pool owner here and trying to figure out the ins and outs. 21 ft above ground pool, around 11,000 gallons. I'm on day 2.5 of slamming and have made good progress, went from green to now a cloudy blue and adjusting chlorine roughly every two hours. Using the Taylor k-2006 kit, my...

Hi, I am noticing what I thought was sand but worry is potentially tiny blobs of algae on the bottom of the pool over the last days and weeks. I would brush it or robot vacuum and it would seem to return in the same areas. No CC readings really ever, but I'm reading that is not necessarily...

I’m a first time pool owner. Pool has been open a little over a month now and is crystal clear but I noticed I was going through chlorine very fast. Did the overnight chlorine test and got FC to 5 last night. Woke up at 5 am this morning before daylight and it was down to 1. Started my SLAM...

Thank you everyone for the collective wisdom, especially as a first time pool owner. I have searched many threads in this forum and learned a great deal. I however wanted to get some feedback. Issue: Day 13 of SLAM and still seeing dead algae. Backstory: We had a pool company and unfortunately...

Hello- I’m dealing with a blue but cloudy pool. I’m fairly sure we had some algae overwinter in the pool due to poor care last year (new baby). I plan to SLAM but my CYA is 0 right now. My question is do I need to get CYA up to 30 before SLAM or do I start SLAM to assess for an ammonia issue...

Hey all! Thank you for taking the time to help out and apologies if this is repeat information. I've had a hard time searching for the answer on this one. Basically, as the title says, what should I worry about balancing before doing a SLAM? Here are the details of my most recent test (1 hour...
