Ascorbic Treatment to rid Pool of metal stains

 

[Knjakeman]

This stuff didn’t do anything but suck all my chlorine

 

[mknauss]

That, is Sodium Bromide. You now have a Bromine pool. Depending on how much bromine is in the pool, you should be prepared to drain and refill to regain your ability manage this pool with chlorine.

 

[Knjakeman]

What? Are you serious?

 

[Knjakeman]

Two cap full in 28,000 gallon pool , and now it’s a bromine pool?

 

[mknauss]

OK -- so you did not add the entire container. Good.

No. That amount of sodium bromide will not effect things. Thank you for clarifying.

Take care.

 

[Knjakeman]

Though I only used two cap fulls of it , I definitely am having an issue with maintaining FC.
FC-0
CC- 0
PH-7.0
TA-70
CYA-70
CH-100
BOR—50
After adding a gallon of 10% chlorine and running salt cell all day and all night.


FC was 5 last night

 

[ajw22]

What test kit are you using?

 

[Knjakeman]

K-2006

Overnight test held at 5 but I checked at noon today with salt cell running and I’ve lost half.

 

[mknauss]

What is the amount of FC being added to your pool each day by the SWCG? T15 generates 1.4 lb of chlorine per 24 hour period set at 100%.

 

[Knjakeman]

I would need to test that tonight.


26700 gal, vinyl, SWG, Hayward Goldline controls, T-15 Cell, 20gpm/ft2 sand filter, 1 hp pump , Taylor K-2006 test kit

 

[mknauss]

Nothing to test. It is a calculation.

Hours your SWCG is on, % setting it is on, resulting in how much chlorine (in ounces) are you adding to the pool each day.

Go to PoolMath, use the Effects of Adding Chemicals. Input gallons of pool, # of ounces and select Chlorine gas.

 

[Knjakeman]

It’s been running 100% for ten hours a day


26700 gal, vinyl, SWG, Hayward Goldline controls, T-15 Cell, 20gpm/ft2 sand filter, 1 hp pump , Taylor K-2006 test kit

 

[mknauss]

The math:
10/24 * 1.4 *16 = 9.3 ounces of chlorine gas per day.

PoolMath. Effects of Adding Chemicals. It is adding 2.6 ppm FC to the pool each day.

That may cover your daily use in the middle of summer.

At a CYA of 70 or 80.
