FC. - 8
CC -1
TC- 9
CYA - 0,
TA -190
Cal Hard- 20
PH - 7.2

Bought a home with a pool, it hasn't been used for over 18 months. All winter I scooped out leaves and debris from bottom. Started with a local pool company 2 months ago, had me add algaecides, chlorine, metal magic after bottom turned orange, a floculant. You get the story.

I received my TF 100 kit today. Above are my numbers. I checked everything twice and cya 3 times. It is an old inground concrete pool, my guess built mid 80's.

Pool has one skimmer, one main drain, 2 return jets, sand filter with multiple settings and a 1 hp pump.

What do I need to do? Attached is a pic to get an idea of where I'm at. It has come a long way from being green!

Welcome to TFP!!!

First, you are going to need to review this if you want to keep updating pictures: How To Post Pictures

With the not clear water and the CC > 0.5, you need to follow the SLAM Process. No need for any of the magic potions the pool store sold you.

First I would add about 30ppm of CYA to the pool (in a sock), then SLAM away assume your CYA level is 30ppm to determine the appropriate FC levels from the FC/CYA Chart. After a week, confirm the CYA level.

Bleach, bleach, and more bleach, Welcome to the forum. You can figure out an approximate gallon size in pool math and base your additions on that. Adjust accordingly for the gallons used per your test results.

Just being overly cautious but you're sure sure sure cya is 0? Test tube filled to top is clear as ever and the black dot is visible? Just making double triple quadruple sure. Since the pool company put so much other stuff in there I'm surprised they didn't put something in that would have added cya since they seem to love to do that..

Anyway, if you're sure you're sure you're sure, then don't let me stop you! Carry on and SLAM away!

I had hard time with cya test at first just in addition it's important that when testing cya the sun is to your back and the test tubs is waist level. This is a difficult test to master but vital to not throwing away money on tons of each just my two cents from having been there

 

[Mudbugs20]

Sorry about the picture. I thought I read everything before making first post. I'm going to check CYA again, it was cloudy at the top but you could still see black dot.

 

[Mudbugs20]

Ok, tested CYA again, at best I would call it 5.

The pool store has a computer to test water sample, they said CYA 55. Said that was ok.

If I'm reading the chorine/cya calculator right, with a cya of 30, I need a shock FC OF 12. Using the pool math calc on 20k gallons, I need to add 241 oz of 8.25% bleach.
To raise cya from a 5 to 30' I need to add 67 oz of stabilizer.

I truly appreciate everyone's thoughts and help.

After the pool store had me put the algaecide in that had copper, they had me use metal magic to clean up stain. I searched this forum and ended up using the ascorbic acid to remove the stains. It worked like magic, my kids were amazed!

You are on the right track----------OWN test kit! SWEET! No pool store for you except to buy pool toys!

Keep up the pics as you SLAM the pool into a full on sparkle!

There is no problem with the pictures, it is just if you try to add many more, you are going to have quota limit issues.

 

[gwc]

Jason I did not realize that there was a limit. I have added many from photobucket.com. Have I done something incorrectly?

Looks like you've been studying! SLAM away!!!

There is only a limit if you attach the file so it is hosted by the forum.

Thanks Jason I did not know that.

Before you add all of that stabilizer to increase your cya ... I would be a bit more cautious and only add 2/3 of that amount - then test a week later and you can add the rest if needed.
