Hello,

I joined here back in 2017 and got some excellent help and ordered the large test kit. Since that time life has gotten in the way and time has gone on. Things had been going fairly well for years and I was occupied doing life things. Last year things started not going so well and I had failed to keep up on my testing practices and although was keeping the chlorinator floater filled and shocking I was continuing to get algae growth weekly. Made it through the season but it was with a lot of scrubbing and plugging up my D.E. Filters which I ended up having to break down and clean up several times last season.

Well here we are again at the beginning of a new year and new season for our pool. It had gotten so bad that after taking a water sample in to Leslies Pool Supply, I was being advised that I needed well over $500 in pool chemicals to get things under control

I purchased a gas powered 2' water pump and adapted my pool vacuum hose to it. After a couple days of scrubbing the sides and bottom the best I could blindly due to the green pond like looking water that I could not see through, vacuumed the entire pool while discharging the water into the back yard. I then switched over to the 2" suction line and completely drained the entire pool all but a couple inches that remained at the bottom. Used a broom and dustpan to sweep up and get out the remaining leaves and debris and refilled the pool. I figured this would be the best avenue and would rather spend the money on the water bill than adding lots of chemicals to try and get our water right again.

I then did a complete tear down of our D.E. 80 Filter system and got it filtering right away. Got the floater full of 3" tabs and also added about 2 lbs. of shock 3 days in a row for a total of 6 lbs. of shock.

I took a sample in to Leslies for analysis, and I will post the results here. I am looking for any and all help from you generous folks here in hopes of getting my brain back on track and my pool water correctly adjusted so we can have a great season this year as well as many years to follow. I will follow your guidance to a T. Thank you in advance for the help, I really appreciate it.

So that is my latest Leslies water test results and advisements. Granted it is now May 6'th but not much has changed and I have been trying to get to this site to see what suggestions I could get before doing anything at all. There is some algae starting to grow on the east side of our pool wall so that was my reminder I need to get some help with this ASAP

Thank you one and all and I look forward to your advice and recommendation's as well as promise to jump right on the actions you deem appropriate and necessary in the order you prescribe.
Any questions you may have, please feel free to ask and I will get you the answers.

  1. Order this, it is the best value: TF-Pro
  2. Get pool math if you don't have it. Link-->PoolMath
  3. Configure your pool in pool math, use the same login/pw as TFP and enable sharing the in gear menu (upper right).
  4. Get 15 gallons of liquid chlorine. Walmart has Pool Essentials liquid chlorine.
  5. Use pool math to determine how much Liquid to add 3ppm.
  6. Add 3ppm of liquid chlorine per DAY until your kit arrives. nothing else.
  7. When your kit arrives, post a full set of results. FC, CC, pH, TA, CH, CYA.

Thank you,

I have Poolmath app on my phone
I picked up 16 gallons of the Pool Essentials liquid chlorine. Its about $6/gl where I live.
I have the TF-100 Test Kit ™ WITH
Optional Items: Speedstir Magnetic Stirrer
Optional Items: XL Option
Although I ordered it in 2017 so I am sure most of the liquids are no longer good 8 years later. I will look for a refill option.
I will post the FC, CC, pH, TA, CH, CYA results as soon as my refill test liquids arrive and I can run the tests.

Any suggestion on which refill option to get for my TF-100 Test Kit? I will search the site and see if I can pick the correct one.

Your reagents are expired. Go direct to TFTestkits to order your refill. Get the one for the TF100 and you might want to add the CYA sample too to help you learn the CYA readings. If you're planning to add a SWG to the pool (highly recommended) then add the Salt Kit to your order.

Thank you,

I have that one in my cart (TF100 Refills)

I have wondered about the SWG and what it would take to get my pool converted over. Do you have any information or guidance in doing this?

For the price of chlorine these days, it may pay off to do this, but I have zero knowledge in the process.

Thank you, I really appreciate everyone here with knowledge and making it shareable.
 
The SWG will save you thousands of dollars in LC over the life of the unit. After the first cell dies down the road (after it has more than paid for itself) replacement cells have quicker paybacks. You have to play the long game with SWG. If you have no automation then a Circupool RJ 60 would be perfect for you. It is double the size of your pool which we recommend. You can usually get it from Discountsaltpools.com for a $10 upcharge from the RJ45. You will need to add a timer so that the SWG turns on AFTER the pump starts and turns off BEFORE the pump turns off so that the cell is not on without water flow. Easy peasy.
 
It is always best to pour the chlorine in front of the returns. That way the pool return’s flow will disperse the chlorine out into the pool. You can always brush the area afterwards.

Thank you, I really appreciate that advice! I think we are sold on the idea.

we have a timer on our main pump as well as on our pool sweep that uses a separate pump. I will research and learn more about those suggestions and see how I might be able to adapt it to our system.

On a side note, as we have algae (greenish / yellow?) starting to form on the east side of our pool wall, my thought is that it would be best to vacuum it off so it gets directly to the D.E. Filter and has less chance to spread rather than just brushing the algae to mix with the water and eventually it will get filtered. I just think vacuum would be the better way to go. I bought a brushed style pyramid looking vacuum with hose from a facebook seller for $25 and thought that might be the best immediate action to take along with adding the 3 ppm of LC each day. Does this sound good?
