Chemicals

[DBarry]

Hello!
New to pool owning and trying to balance my own chemicals. We just opened and I used the TFpro for the first time.

1. Which chlorine test should I use initially?
2. Do you test one at a time, add a chemical and then continue with each test or test all of it at once and then just add chemicals based on the calculator here?
3. Our calcium was low at 200. The app says to add 109lbs of calcium! Does this sound right?

Thanks for any help!

Welcome to TFP.

Always use the FAS/DPD drop test chlorine test.

Run the whole battery of tests to get a complete picture and then plan what chemicals to add in what sequence.

How many gallons in your pool?

For a plaster pool, you only need to raise your CH to 250-300 ppm. Don't blindly follow PoolMath settings and targets. You need to set up the calculator for your unique pool and environment.

What is the pH, TA, and CH of your fill water?

It is about 45,000gallons. 20x40 and 10’ deep end.

PH 8.2
Bromine 1
Total Chlorine 0.5
Total Alkalinity 100
CYA 40
Calcium 200
Haven’t tested FC yet. We haven’t shocked it yet. Is “shocking” different than just adding chlorine? Does it need to be shocked? It’s quite clear on opening. You can see all the way to the bottom and it’s not cloudy.

Thanks so much!

Is your pool bromine or chlorine?

Why are you reporting bromine?

Chlorine is the chemical that keeps your pool sanitary and algae-free. It is important to maintain the proper FC/CYA level.

A clear pool is not necessarily a sanitary pool or algae-free pool. Only the correct chlorine level and passing a Overnight Chlorine Loss Test will demonstrate the pool is sanitary and algae free.

You never need to shock a pool if you maintain the correct FC level.

I will take a look at those resources to get the right levels. It looks like my pool math app has been set up for my specific pool. Sorry, it’s chlorine, not bromine!

Do not follow the robot blindly.

PoolMath does not know the specifics of your pool and environment. It is a calculator that needs to be adjusted for your specifics.
