Got test kit and Im concerned now.

Postby another nowbie post » Thu 08 May, 2008 09:27

Readings are as follows:

FC 10
TC 10
BR 10
PH 7.4
TA 80
Cal Hard 200-250
CYA 35-40

The pool is very clear, still getting stuff gathering on bottom after having the pump off for few hours.

I thought my chlorine was higher then this but the test doesnt lie. SHould I be concerned about having a combined Chlorine of ZERO?

Gonna read the taylor book to see what this pretty circle dial thingy is now, lol.

Also what reccomended chlorine levels do you think I should try to maintain with these readings and a 22,500 gallon pool.

Cleared this up with bleach, currently using last of the pucks I have then will go back to only the BBB you guys recommended.

Thanks for all the help, since I started getting help here and not the pool store I spend less then 30 bucks to clear this up.

Having a Combined Chorine (CC) of zero is good and is what you want.

To keep away algae, you need a minimum Free Chlorine (FC) level that is at least 7.5% of the Cyanuric Acid (CYA) level and targeting 10% gives you some cushion. So with around 40 ppm CYA I would target 4 ppm FC. If it drops briefly to 3 ppm, no big deal, but don't let it get below that. Since you'll probably lose 2 ppm per day, you'll add chlorine at night to get to 6 ppm, most likely, but see how things go.

You can consider automating your chlorine dosing using either unscented bleach (e.g. 6% Clorox Regular or off-brand Ultra) or chlorinating liquid by using The Liquidator which you can read more about in this thread.
