When we took the cover off, the pool was brown. I took a water sample to pool store. After 2 rounds of shock with algae all, then 20 pounds of chlorine, the pool is blue, cloudy and reading zero for both ph and chlorine. I ordered a kit but for now I'm using the 3 way test kit. I've taken samples 3 times to pool company. $300 later, still no reading. Any suggestions?

Welcome to posting on the forum!
What kit did you order?
While you are waiting on your test kit, add 5 ppm FC worth of liquid chlorine / plain bleach to your pool each evening with the pump running. This will replenish the FC lost each day to the sun and also inhibit any algae in the water from growing further.
I suggest you read ABC's of Pool Water Chemistry.

I ordered the tf100 test kit. Thank you.

If I have 16000 gallons of water in the pool, how much liquid chlorine would I need to add daily until the test arrives?

 

[mknauss]

Using Effects of Adding Chemicals in PoolMath, you would add 3 quarts (96oz) of 10% liquid chlorine to add just under 5ppm FC per day.

Thank you.

I received the test kit today
Here's my numbers:
FC .5
CC 1.0
CH 1000
ALK 200
CYA 50
PH 7.5
still cloudy but I can see floor drains.
I tried entering numbers in pool math but it's only calculating chlorine.
Recommendations are welcome! Thank you!

I had the info all typed-out before I realized your CH level. 1,000? Let's be sure of that one. 10 drops of #10, 3 drops of #11, then count each drop of #12 as 25 ppm for each drop. The solution should change from a light purple to a light baby blue. That baby blue is when you are done. Please report back with the CH one more time to be sure.


We'll come back to this stuff later (after the CH confirmation):
So with cloudiness and an elevated CC level it appears you have some algae trying to grow and a SLAM Process will be warranted. Can you update your signature please with all of your pool and equipment info to include the test kit you are now using? That will drive future replies.

For the water, lower the pH slightly to about 7.2 with muriatic acid, then increase your FC level to "20" using liquid chlorine which is your SLAM FC level per the FC/CYA Levels. Maintain that FC of 20 as best as you can day and evening until you pass all3 SLAM criteria. Stick to that SLAM page and you'll do fine.

I just did the CH again and it's purple after 40 drops

Is your tap water very high in calcium? Do you have a water softener for your home? Or have you used Cal Hypo to chlorinate the pool water?

So... we did not add any water to the pool yet this year...all rain and snow...but the pool store had me add 12 pounds of balance pak 300 on June 1.

Is this a vinyl liner pool? Regardless, you did not need to add the calcium chloride. That amount was 80 ppm CH. So a lot of calcium came from somewhere else.

What was the 20 pounds of chlorine used? Bags of granules? If so do you remember the brand?

Yes. Vinyl line
