Fill Water Test

[aretha1075]

Woohoo my test kit came today and I have fill water numbers.

Cl- 0
Ph- 7.2
FC- 0
T.C- 0
T.A.- 210
CH- 250
CYA- 0

Now that we have numbers I have a few questions.

1. Do I need to use "shock" powder to get the clorine and CYA to correct levels?
2. If so, approx how much to I need to get?
3. If no, please tell me what to get and approx. how much?

I know to get borax, baking soda, and stabilizer. I already have muratic acid.

For the blonde question of the day.... What is the best measuring tool for adding chemicals? I am thinking just regular kitchen measuring cups and a glass measuring cup that goes to 4 cups.

Thanks for helping!

Welcome!

You can use Di-chlor powder to add both chlorine and stabilizer. It's much simpler to buy the two ingredients separately, though, especially since you're unfamiliar with http://www.poolcalculator.com/

You do not need borax right now. The TA is high enough that the pH will likely rise just from the agitation of filling the pool, and 7.2 is fine right now. Baking soda raises TA, and you don't need any. You may never need any more, with the high TA of your refill water. I've never added any to my pool in three years!

The acid will be necessary eventually, and it keeps for years, so you're good there. You should use http://www.poolcalculator.com/ to calculate how much CYA you need and buy enough. Also, pick up a few gallons of either bleach or "liquid shock." Same stuff, different concentration is all.

The answers are in Pool School, including a how-to use the http://www.poolcalculator.com/ and how to add the various chemicals. You might as well start learning now; having someone else tell you what to add is the pool-store way.

I will just add that you may not want to use a glass measuring cup by the pool. If you drop it, you will have glass everywhere. Plastic is much safer.
