Hello Everyone!

Firstly, I'm new to the forum so thank you for all of your help. Here's the situation.. My girlfriend and I just bought a house back in February that has a 24 Foot Metal Sided Above Ground pool on the property. When we bought the house, there was a cover over the pool that looked to be in decent condition, so we assumed it had been properly closed. Boy were we wrong..

We knew the house had sat vacant for approximately 3 years prior to us purchasing it, and later found out according to the neighbor, the previous owner, who moved in approximately 3 years before the "3 year vacant period", never used the pool, so we now assume this pool has sat for at least 6 years. With that being said, I went outside one day and found one edge of the cover had slid free of it's cable and fallen into the pool. My girlfriend and I decided to go ahead and remove the cover and we would just start the opening process a little earlier than usual. (This was sometime in March of this year). To our surprise once we pulled the cover off and pulled the water pillows OUT of the pool, I found another cover that had fallen apart and sunk into the pool. This leads me to believe the pool was probably covered when the previous owner bought the house, and at some point during her tenure, the cover gave out due to age and breakdown from the sun, and fell in. We then believe she just left it right until she was getting ready to sell the house, at which point they put a new cover over it to make it look like the pool had been cared for.

So here's the real issue.. there is ALL KINDS of stuff in the bottom of this pool. We have spent the better part of the last month trying to clean the bottom of this pool out with a net. We've gotten A LOT of junk off the bottom, but I'm relatively sure that a good amount still remains. A couple of week ago I finally started adding chemical to the water. I started with some Green to Clean and then LOTS of shock. According to our latest test, the pool is now finally holding chlorine, as a matter of fact our FAC is actually a little high now so we're working on bringing that down just a tad.

I've vacuumed what I can see of the bottom of the pool twice now, and have had decent results, and am starting to be able to see the "white" color of the bottom in places but the pool is still pretty cloudy, and there's definitely still stuff at the bottom. I've also tried a clear aid in an attempt to get the water to clear up enough to be able to clearly see the solids and stuff at the bottom that need to come out.

Why am I here? I'm here because everytime I take a sample to our local pool store they basically keep telling me the same thing.. Add these chemicals, get the stuff off the bottom. I get that, and maybe that's really all that can be done, but I feel like I'm just throwing money in at this point and getting nowhere. I guess I'm just asking if anyone has experience with something similar to this and knows a good trick for handling this a bit quicker/more effeciently.

Here's what's been done so far:

Filter Sand Changed a Week Ago
Approx. 15-16LBS Chlorinated Shock Added Over the Last Week or So.
Green to Clean
Clear Aid
Pump Has Been Running Nonstop for About 2 Weeks.

I've attached a picture of what the water looks like currently.
 
Hi and Welcome to TFP!!! NO more pool $tore for you!!! They like to do "free" tests but as you found it is not really free if you walk out with your arms full and wallet empty :(

Now take a deep breath. I am going to lay some info on you that you will LOVE! You can get that pool clear using liquid chlorine!!! Well and a bit of vacuuming as well. We can help you do it as that is why this site was started! I was right were you are when I found TFP so I know what you have going through!

There is one thing you need to do...............get your own test kit............OH NO KIM! I have already spent so much money................I know but this is a must have for what YOU CAN DO to clear up that pool and have it ready to swim in and enjoy! Here is the test kits we use: Test Kits Compared I will tell you I suggest you get the TF-100 XL as it will have more of the regents you need to fix up your pool.

What you are going to do is what we call a SLAM SLAM Process This is a tried and true process for clearing up PONDS pools. Until you get your test kit what you should do is find a place that sells liquid chlorine in your area. Your pool store might sell it in their yellow jugs. If not then it can be found at Walmart in white jugs. Home Depot and Lowes sells it also BUT you have to know how to read date codes to make sure it is not older than 3 months.

Once you find and bet about 10 gallons of liquid chlorine you should add about 1/2 gallon of chlorine to the pool each evening to keep the pool from reverting to a pond. Keep the pump running like you have and brush the pool (yeah it will look worse afterwards but....) to get all of the gunk up into the water for the chlorine to work on and maybe into the filter.

We can help you get the pool clean and clear and save you a LOT of money compared to the pool $tore! We do not sell you ANYTHING. We work for smiles and seeing ponds turn into pool! :hug:

Congrats on the new pool!
There’s a definite positive here - that it holds water💧!
Do as Kim said & get a test kit ordered ASAP-
Get a good supply of liquid chlorine
& read through the SLAM Process & ABCs of Pool Water Chemistry to get prepared for action when your kit arrives.
No sense in wasting $$ on random stuff while u are flying blind - just add the 5ppm of liquid chlorine daily to keep it from getting worse (use PoolMath to calculate amounts) &
keep vacuuming/brushing daily until you have some reliable data to start with .
Backwash whenever filter pressure rises 25% over clean pressure.
When your kit comes - do all the tests & post them here. We’ll be waiting for u 😊
 
Just wanted to give everyone an update..

Life's been pretty busy since I posted this, so admittedly I haven't done much to the pool, but the pump HAS been running non-stop still so I suppose that's still good. I was able to find some Liquid Chlorinator relatively cheap at our local Rural King so I picked up 4 gallons of that Friday, went ahead and did what it recommended for "opening" which I think they called "Super Shock", pouring 2 bottles into it immediately, then pouring a third in the next day. Water didn't really clear up any, but there should at least be ~SOME~ chlorine staying in there now to keep it from going full blown swamp again.

I was also able to get in it with a vacuum again today. This time I actually got in the pool and walked around with the vacuum, and to my surprise the bottom of the pool is actually much cleaner than I originally thought. Going to add another bottle of chlorine tonight after I get done refilling it (lost about 6 inches after a loooong vacuum). I've also gone ahead and ordered the TF-100 test kit, so hopefully it will be here sometime this week.

Thanks for the warm welcome and I hope to update with good news soon!
 
When your kit comes in run all the tests & report back. Until then just keep with the 5ppm of liquid chlorine each day to keep things at bay .

If water is cheap and you have a good direction to drain it, it would be alot easier to drain most of the pool. It would be super easier to get the crud out when it was floating in a foot of water instead of 4. Then upon refilling you would only be battling that 25% of old water which would go that much quicker.

We will gladly help you either way. :)

Firstly, thank you to everyone for all of the help so far. My TF-100 got delivered today so I finally got the chance to properly test my pool water on my own. With that being said, I've entered the results into the Pool Math app, that I believe is recommended on this forum somewhere.

Here's a link to the results: PoolMath Logs

With that being said, should I go ahead and proceed with the "SLAM" process or is there something else I should do?

I've also attached a picture of what the pool looks like now.

Proceed with SLAM Process - testing & replenishing 12ppm fc FC/CYA Levels as often as u can, every couple hours if u can swing it. The more often u test & replenish fc the faster it will go.
Pull that ladder ASAP & scrub it with bleach inside & out. If it has water in it u can bet it’s algae city.
Brush/vac daily & backwash/clean your filter when pressure rises 25% over clean pressure.
SLAM ON 👍🏻
During slam just focus on testing fc & cc
 
Full speed ahead !!! You'll want to test and add as often as possible. 2-3 hours is best for the first day or two and the more time it spends 'M'-aintaining SLAM, the quicker it will go. When life gets in the way, do the best you can.

If it hasn't cleared alot by the weekend, plan on running your errands around testing times. You can top it off and go out to dinner (etc) buying yourself the next couple hours away.

Awesome, thanks again for the help.

Just went and stocked up on Liquid Chlorine and added 2 gallons then tested.

FC is now 17.5ppm
CC is 1ppm
and TC is 18.5ppm

So if I understand the process this looks good so far, and just need to maintain FC at or over 12ppm, obviously the closer to 12 the better, right? And then obviously brushing and vacuuming daily.
 
Going over isn’t necessary & wastes chlorine to the sun ☀️ 1ppm or so over is ok but any higher is just a waste of $$ & risks damage to surfaces, equipment, & swimmers.

PoolMath This is my best pool friend! It tells me just how much to add for go from here to there! It does all of the math and thinking for me!
Ah, I was getting to reply "Well it doesn't show what should be added to get to "SLAM" levels as it's just trying to get it into the "balanced" level, but I completely forgot there's a SLAM option there. Whoops, okay, will be going by that then from now on. Thanks for that little unintentional reminder haha.

As far as current results, so as I stated in my earlier post, added 2 Gallons of Liquid Chlorine at 9:00P.M. last night, which brought my FC up to 17.5, obviously well above 12. (Now that I've remembered the SLAM option for PoolMath, I should be able to keep this much closer to 12 once it comes back down to earth lol.

Checked chlorine again this morning at 8:00A.M. and got an FC of 16.5 and CC of 1. Water condition obviously hasn't changed much overnight, but otherwise everything is looking on track right?
 
CC are a bit high and 1ppm loss is just barely failing the OCLT, but it's a good sign that your algae are mostly dead. Keep filtering the water. Sand filters are the slowest to clear, but if you keep your pump running and keep up with the scrubbing and vacuuming, it'll get there. It can take days or even a week or two sometimes, and yours was pretty dirty to start. Taking a photo each day of your pole/brush going down to the bottom of the pool can help you see progress being made. :)
 
So just wanted to update everyone with my progress so far. Although there hasn't been much progress visually yet, I'm not expecting overnight results and today marks the 2nd full day of SLAMing. I've also been taking relatively detailed notes as far as what my test results have been and what I've been doing to the water. Please let me know if there's anything else I should be doing or if there's something I'm doing incorrectly. Keep in mind I'm testing as often as possible given that I work from 9AM to 6PM every day during the week. Here's the notes:

6/6/22 @ 9:00P.M. - Removed latter as advised on TFP. Will clean when I get time. Added two gallons of liquid chlorine. Will check FC and CC levels within the hour.

6/6/22 @ 9:43P.M. - Tested chlorine levels and found the following:
  • FC = 17.5ppm
  • CC = 1
  • TC = 18ppm
6/7/22 @ 8:00A.M. - Tested chlorine levels again and found the following:
  • FC = 16.5ppm
  • CC = 1
  • TC = 17.5ppm
6/7/22 @ 2:00P.M. - Tested chlorine levels and found the following:
  • FC = 11.5ppm
  • CC = 1
  • TC = 12.5ppm
6/7/22 @ 6:30-7:30P.M. - Thoroughly brushed sides and floor of pool, vacuumed to waste, then backwashed filter. Will let sit for a bit before testing water. (Also rained a considerable amount today.)

6/7/22 @ 8:00P.M. - Tested chlorine levels and found the following:
  • FC = 6.5ppm
  • CC = 0.5
  • TC = 7ppm

Added the recommended 95oz of Liquid Chlorine (to bring FC back up to 12) and will retest before bed and add more if required.

6/7/22 @ 11:30P.M. - Tested chlorine and cyanuric acid levels and found the following:
  • FC = 11ppm
  • CC = 0.5
  • TC = 11.5ppm
  • CYA = 30

Added recommended 17oz of Liquid Chlorine to bring FC up to 12 and maintain overnight.

6/8/22 @ 8:00A.M. - Tested chlorine levels and found the following:
  • FC = 9.5ppm
  • CC = 0.5
  • TC = 10ppm
Added 43oz of Liquid Chlorine per PoolMath suggestions to bring FC back up to 12.

6/8/22 @ 1:30P.M. - Tested chlorine levels and found the following:
  • FC = 8ppm
  • CC = 0.5
  • TC = 8.5ppm
Added the recommended 69oz of Liquid Chlorine to the pool.

Okay, so how's everything sound? Good I hope. Also have a few questions. When vacuuming daily, should I be vacuuming to waste or running it through the sand filter? Last night I vacuumed to waste just because I wasn't sure, so figured I'd ask. Also, in one of the pictures attached, you'll see a bunch of really small black particles floating around. Any idea how to go about getting rid of these? They've been in the pool for over a month now and it seems like they may be too small to be filtered out by the sand. Finally, also attached a picture with one of my poles in the water for an idea on current clarity as of today.

Thanks again for everything everyone!

Vacuuming to waste isn't a bad idea as long as you understand you'll need to replace the FC that you're also draining out.

You are right on the verge of that water turning blue. Keep up the SLAMMING and I predict you'll see a big color change in the next day or two.

After that it's just a matter of waiting for the filter to clear out all the dead algae.
 
You are SO on the right track!!! I am very impressed with what you have been able to do while working!

Are you leaving the pump on 24/7? If not you need to do so.

What was your last CYA level? Remember you will need to keep an eye on that when you take water out as well.

You can vacuum to waste if you want to as that will get some of the yuck out but remember to keep an eye on the CYA and FC.
 
Sand filters can make a pool this clear:


So it'll get the black stuff too.
