Rant Incoming! tl;dr: My pool is greenish/brown. I recently double shocked it and have been using Clear-Aid, to no avail. I don't know how to proceed.

Good afternoon! I hate that my first post has to be a post requesting help, but I am at my wits end. I am so frustrated and tired of working on this pool. We bought a Vinyl AGP 32'x16'x48" roughly two months ago. Chemical wise, things were great for about a month, then it wasn't. I live in a small town east of Houston and was relying on the Leslie's in town to help with all my chemical needs. Again, at first, everything was fine. Roughly 4 weeks ago, the pool got cloudy. Took a sample to Leslie's and was told it was all good, use a clarifier. I bought Ultra Brite, at their recommendation. I shocked the pool that evening and used the clarifier the following evening. We had to leave town for about a week and showed my oldest son what to do while we were gone, but nothing major should happen as everything appeared to be good. The second day we were gone my son called saying the pool was green. I thought, no way, not that fast. He sent me a pic and it sure was. I told him to sweep the walls/floor and keep stirring it up. Showed him how to clean the sand filter and asked him to take a sample to Leslie's. Wow, another "No Problem" result! "How could this be?" I asked. They said it was probably the weather, asked me to tun my pump for a couple of extra hours and "It'll be fine". Came back to town a few days later, and it wasn't any better, but I don't think it was really any worse from the pictures. Leslie's recommended to shock and to follow up with Clear-Aid. Finally, after a week of Clear-Aid and cleaning the filter every morning, the water started clearing up, but it wasn't getting clear, it was just dirty looking, a light dingy brown color. Took another sample to Leslie's, CH was low, bought Hardness Plus and more Clear-Aid. Shocked again and waited the 48 hours before adding more Clear-Aid. The next day, the pool was green, like we hadn't done anything for the last 1-1.5 weeks. Went back to Leslie's with another sample, now the Alkalinity is low, but other than that, their system shows ok. Explain once again what's happening and the lady asks how often I am shocking the pool. Once a week, to which she tells me that it should be done twice a week right now due to the heat and that is what they have been telling their customers. Now, if you have been following the story you would know that I have been to Leslie's at least 6-7 times in a month, her helping me each time, and not once has she told me to shock my pool twice a week. At this point, I am beyond frustrated. She advises me to double shock the pool, shock it today (Saturday, 6 Aug 22), wait 24 hours, shock again. I have spent probably close to $800 in the last 3 weeks trying to fix this Dang thing and I'm right back at square one. I am fully prepared to stop using Leslie's and to purchase my own water test kit. What can I do to clear up my pool?

Now, being in Houston, I can use my pool for a while longer than some places as it stays hot here, but we are losing good swimming time. My wife is mad with the pool, and that is more important than anything else right now! LOL. Thanks in advance, if you need anything, information or otherwise, please feel free to ask. I believe I have the relevant info in my signature.
 
Hi, Welcome to TFP!! :swim:

If you go back through my posts, I experienced the same thing, almost word for wordm when I came here. I am PoolStored.

Start here --> Pool Care Basics
Get a test kit, TODAY --> Test Kits Compared
Download Pool Math if you have a smartphone --> PoolMath

ADD NOTHING to your pool until your test kit arrives, except, add 5ppm of liquid chlorine a day. This will keep the algae at bay until we get test kit in hand.

We can help you get your pool in hand...
 
Thank you, @PoolStored. I will go through your post history; I am purchasing the TF Pro right now. How do I determine 5ppm of liquid chlorine if I do not know my CYA?
Great Question!!!!

Download Pool Math and configure your pool. Click the 3 bars in the upper left and choose "effects of adding" from the menu.

You do not need to know your CYA to determine how much chlorine to put in your pool to add 5ppm per day.

Yere is the shorthand version (link below). GET THE SMART STIR, will change your life. Smart Stir, Robot, SWCG and Hairnets. Take them away, I fill in the pool (well maybe not the hairnets). LOL

To help ease your mind a little I was in almost the exact place as you about 6 weeks ago. I had been to the pool store 20 times with 20-50 spent each trip. I found this site and with the help of the amazing people here I have a crystal clear pool for me and the family. The first part of doing the slam is grueling and seems endless for a few days. Once that is done I now spend probably 45 minutes a week in testing and staying on target. Plus I now spend 20 every 10-14 days on 1 case of liquid chlorine

OK, let me know if I did this right, please. At roughly 14.5k gallons, using an 8.25% bleach concentration, I should add almost 1 gallon? The app says it would raise my FC to 5.0
 
How are you chlorinating your pool? (not shock, just daily chlorination?)
The 3" tablets. Roughly 3 per week.

Thanks for that. Ya, it seems this is the way to go. I've been trying to read the Pool School and various posts since yesterday.

You got it. 110 ounces. Add it daily.

I would remove the tablets. You likely have very high CYA and have not been able to keep enough FC in your water to sanitize. Use liquid chlorine until you get your test kit.

First pic is start 2nd is 1 week later using the SLAM process. It does work, and when you first open your test kit you will think omg how do I do this but most of the test are very simple to complete

Ok. Thanks for double checking me. My wife found 10% so I redid the math and it comes out to 93 oz. I did order the TF-100 pro with the smart stir and will wait impatiently for it to come. I will remove the chlorinator and just use the bleach in the evening. How long should the pump run for during the day? I was running it previously about 9 hours. It’s been running non stop to try and get this cleared up. I read you should run it thirty minutes after adding your chemicals near the returns to get them mixed around, but didn’t see anything concrete with running during the day.

Great on the math. That's why you need Pool Math. Great tool.

So, on the pump, you likely have algae. You have a pretty big pool and that pump is rated for a 17K pool. You are going to kill some stuff with the Chlorine. You want to get it out. I would run your pump 24x7, but you will have to watch it. Go backwash the pool now. Follow the instructions in the manual carefully (i.e. don't move the valve with the pump on). Manual below. NOTE YOUR PUMP PRESSURE. When the pressure rises 25% from clean, backwash again. This will protect your pump. For the AGPs with algae some will go 6 hours before it rises, some 12, some 24. Depends on the filter and how bad your algae is. Do you have a vacuum or robot? (I suspect not).

You run your pump for a purpose. Mixing chemicals, filtering, skimming, vacuuming. If you pool is clean and all you need is mixing 30 minutes is fine. At this point, we are going to want to filter all that stuff out. When your test kit gets here, we will make some adjustments. Then we will likely do two things.

1) It is highly probable that your CYA is too high. The only way that we can get CYA out of the pool is to to a water exchange/Drain. Read up on that with this link. We won't know if we need to drain until we have the test kit to KNOW what your CYA level really is...
2) We are then going to SLAM your pool. This is a one time thing, IF you maintain your pool properly going forward. Read this. Three times. Print it out. It will be the next step in the process. Read it again. Each time you read it you will say, "AHA." Ask any questions!

 
@PoolStored, apologies for the delay. I do not have a vacuum, robot or manual. My returns are configured with built in strainers and wouldn’t do very well, in my opinion. It would work with dust/algae/etc. but as soon as a leaf got sucked in, I’d have to take it all apart and clean it. A lazy excuse, I know. I plan to perform a 1.5” PVC upgrade and upgrade my returns to 1.5” also so I can use a vacuum more effectively.

Thank you for posting all the information. I’m a digital guy and have all manuals downloaded to my phone for easy reading and searching, lol. I know, I’m a nerd. Anyway, I backwash once a week minimum, but have been doing this daily/every other day (depending on gauge) since trying to clean this mess.

I used the liquid chlorine last night and let it do it’s thing. Got home from work this evening and noticed it was looking better already. I brushed all surfaces and put another dose of LC in. I was surprised at how clear it looked already and am hopeful this won’t take as long as I thought. I’m hoping for the best, but I’ve planned for the worst.

Hopefully the test kit will be here soon; I was surprised it hadn’t shipped yet. This gives me an opportunity to practice my patience, a trait I have never been very good with. Thanks again for all your help! I really appreciate it. Looking forward to this getting cleaned up and enjoying what’s left of our summer.

@SkW3rL Good job. We call it POP (Pool owner patience).

Just add 5ppm per day. They usually are good on getting stuff out fairly quickly.
Ok, I received my TF-Pro today. The SmartStir was not in it as they are backordered, so I guess I'll have to caveman the test. Please advise on the tests I need to complete. I know I need to run the full gamut on my pool, and I'll need to read through the kit and learn how to do everything. I've owned test kits in the past, I believe it was just the DPD kit from Leslie's, so I have some knowledge on how to perform the tests, but it has been close to 10 years since my last pool. Pool looks really good today, too. It is more cloudy than algae looking now.

Great, do all the tests. This link has extended instructions and tips. Print them out, really helped me. Read them 3 times and go. Easy. Post them and we go from there...

It's possible that your 5ppm was enough to kill the algae. If that's the case, then your CYA likely isn't super high, or the algae bloom was just starting and wasn't very thick yet. Both are good things.

You'll still want to post your test results here and then do the SLAM Process to completion to make sure it doesn't backslide and that you don't add TOO much chlorine at any given time, which risks making your FC too high for your CYA and damaging pool surfaces/equipment. PoolStored is doing awesome with helping you out, follow his advice :D

Well, I read the instructions that came with the kit, super simple, but I'll read through those as well. Here are my findings:

pH - 7.5
FC - 12ppm
CC - 0.5ppm
TC - 12.5ppm
CH - 300ppm
TA - 90
CYA - 60

I did the CYA test twice just to ensure I saw the dot disappear accurately and came out both times with the water line on the 60 mark. If something doesn't look right, please let me know and I can do it again, but I'm pretty confident these were done correctly.

Thanks @IceShadow, so far so good. And it doesn't seem as though my levels are too far out of whack, which I imagine is a good thing. It looks like with a CYA of 60 I should have an FC of roughly 7-9ppm?
 
For normal use, yes. For now, though, you're going to want to start the SLAM Process which basically means you're targeting a larger number than standard and testing/adding chlorine as often as you can (up to once an hour, at least 3 times a day) so that everything for sure is dead. Target at CYA of 60 for your FC for the SLAM is 24, so that's what you want.

First, though, let your FC fall below 10ppm temporarily and test the pH again. That test is no good at FC above 10ppm, so let it fall and test again. We just want to be sure your pH isn't totally out of whack before the SLAM really gets going.

(You can skip the TC test by the way - the FC and CC is enough to tell you what you need to know about the chlorine levels.)
