Howdy TFP, I've been trying to get my pool to Shock level for the past 36 hours with little success. The pool math app keeps advising to add 2 gallons of 10% chlorine every time I test but I can't seem to get above ~2 FC. I'll even test 15 minutes after adding to see if I get a quick spike but...

Quick background: After purchasing a new home that came with a pool, I knew my knowledge was at a solid zero and that I'd need some major help. We turned to the company that the home's previous owners used to open/close the pool which informed us they no longer serviced our area. So I did some...

Hello all! I have had this pool for 10 years now. This is the first time I have opened the pool w/ the new pump and cartridge filter. I am running the pump at a constant 3150 RPM. The flow rate says ~80 GPM Depending on how many leaves have fallen into the pool/skimmer basket. The PSI on the...

Over the past few months, I have become the "chemical czar" over 800,000 gallons spread out over four pools in three locations. This has been a 100% learning by doing, TFP and YouTube exercise. In the land of the blind, the one-eyed man is King. One of my outdoor pools is a 126,000-gallon...

Stay true to the Slam Process, it works. One thing I will say though, make sure your equipment is working effectively. For the last 2 seasons I had my pool chemistry on point but the pool didn’t look like I wanted it too. I finally cut the piping this year to open up the sand filter and there...

Hi Everyone - I have some questions about pool opening and pool covers. I have an old loop-loc cover that probably is in need of replacement. Each spring, I spend about a week sanitizing the water in my 43k gallon pool. When I remove the cover, the water is black – it’s disgusting. It entails a...

Hey everyone! Opened the pool today to no algae and just some cloudiness (yay). Most recent test results and log attached. Based on these results is it ok to start slamming? I’m mostly concerned since the pH is slightly lower than the recommended levels here on TFP to do so. Thanks for reading...

I needed to SLAM my pool while opening--it had a green tinge and 0 FC. I used roughly the same amounts of chlorine to do it as I did the last time I SLAM-ed, forgetting that I added CYA since then and need way more chlorine than what I remembered to reach SLAM levels. I've already passed an...

I am two weeks into a SLAM to get my 26K gallon AG pool operational. I have seemingly tried everything under the sun to get my pool clear - it is currently a cloudy light blue and has not improved much over the last week (maybe 5% better in one week). If I look closely I can barely see my pool...

Hi All, I'm preparing to do my first SLAM starting Thursday night. I'm keeping my water balanced as best as I can until then. I'm waiting until then so I can give it the attention that is needed. Also, it is supposed to rain today and tomorrow, so I'm hoping that will drop my CYA to an...

Just bought a house that the owners didn't take care of the pool very well. It's 35k gallons with sand filter and SWG (not using yet due to swamp). CYA was below min reading of test, so been working on adding enough CYA to get to 40ppm and using a FC target of 20ppm. SLAMed for 2 days, using 24...

I've SLAMmed it several times, and the best I can do is 0.8. If I don't SLAM on the reg, it will be between 1 and 2. I figure I must be doing something wrong for my setup. Here are the factors that I think are influencing my process: My < 1 year old tub came with an ozonator It's under a tree...

Hey all, First, thank you for this forum. I've learned a lot! I think I'm also very confused. After having some company for the weekend, I noticed that my FC went to 0. I decided to do a SLAM to bring it back to health. Post SLAM, FC levels (once I started measuring again) went from 12 to 5 in...

Hi all, just had my pool totally redone (plumbing, pebbletec, filter and pump), and I got lazy with my chlorine and now it's green. Since some of my test results are weird, I wanted to check before I SLAMmed. My CYA is very low, so would like some advice before I start. 15,000 gal pool -...

Hey there y'all! New to having a pool this year and have been dealing with brownish yellow dust for the past month or so. I have used Yellow Out and done the full cycle and Green to Clean and done the full cycle and am still dealing with the same issue. There is a fine yellow brown dust coating...

First year pool owner. I’ve been following the pool stores directions on how to care for my pool. The pool store is also the same company that put the pool in for full disclosure. My pool is now completely green. They keep selling me I’ll decide to pour into it and telling me to turn my...

So, back in July I went through a algae problem which I was able to successfully overcome through SLAM. However, since then, I feel like it comes back so easily even though I have been making sure to keep the chlorine over the recommended levels for my CYA and I feel like I am constantly running...

What? I started my SLAM at 40 CYA, using liquid chlorine, 8.25% Sodium Hypochlorite. I just finished my slam, checking my levels and they are: FC: 13.5 CC: 0 CYA: 100 Where did this CYA come from???

There's been a bit of a heat wave in southern Ontario and my pool got away from me. Noticed some green sediment on the bottom. About to start a slam, but the dolphin has been sitting in there for a couple days. I see lots of threads about whether it's helpful to run the robot, but that not my...

Hi! Do I need to slam? My pool data is: FC: 0.4 CC: 0.2 pH: 8 TA: 110 CYA: 50 Thanks!

Hey all I have a "what if" scenario.. If you are not entirely sure what the cya level is..in my example Im pretty sure I can't see dot at 40ppm cya so I rounded up to 50 cya...I am slamming at 20ppm chlorine. Now say it really is 40ppm cya and I'm calling it at 50..is it safe for my family to...

First time pool owner. I forgot to add chlorine to pool going away for a long weekend, and came back to a green pool. That Tuesday I followed the advice on the taylor kit booklet table in the back and added 4 gallons of chlorine to add 30 ppm. Killed the algae overnight since the pool was blue...

Backstory: Bought house with pool in January. Got it going good with yalls advise. I bought a stenner pump and a drum of chlorine. its been going good. I go on vacation last week, i thought i had plenty chlorine in the stenner but i was wrong. Got home saturday to a very green pool. I poured a...

I’ve been SLAM’ing for close to a week - my second time doing so because I think I jumped the gun a day or two early last time I believe. I have passed the OCLT three mornings in a row. CC is virtually zero. But there is still a small amount of mustard algae every 12 hours or so, when I vacuum...

Latest test results: Calcium - 450 TA - 90 CYA - 70 pH - above 8.2 Salt - 3200 FC - 1.5 CC - .5 TC - 2 We have been getting a few monsoon storms lately in AZ. Last week I had to drain some water out. The water level was just under the concrete walkway. FC is really low, that's why I'm thinking...

I am taking over a pool on a new house that I just bought. Still waiting for my test kit to see just what the water looks like from the items I can test, but regardless of what I get from the test I've been mulling over doing a water exchange just so I can start with a clean-ish slate. My pool...

I am in my 1st SLAM and am having a hard time testing FC due to my Taylor kit only reading up to 10ppm. I have tried to half the test but don't feel I am getting a good read. Do you all have any suggestions of tests that read higher FC? I am supposed to be staying at 24ppm and can not verify...

I am in the process of SLAMing my pool, using the TF-100 test kit. I brought my water sample into Leslies to compare my results. I was surprised how different my measures were than Leslie's - and I'm wondering folk's opinion of the accuracy of Leslie's testing? Should I use Leslie's results...

Hello again, This last weekend I changed the sand in my filter, retightened all the connections, and drained and replaced more than half the water (removing algae and higher copper levels from previous system). I tested the water Saturday afternoon and continued with SLAM. FC 8 CC .5 PH 7.2...

Hello- I just discovered the TFP website a few days ago and got right to work. We put in our first pool last year and spent too much time and money at the pool store only to continue to always have problems so I am excited to get on board with TFP! My question is: we are currently SLAMming due...
