Hi All,
I have done a bit of reading and successfully used the 3 step bromine process for the previous 6 months.
I emptied the spa and refilled 2 weeks ago but this time I'm struggling. Any help would be appreciated please
The spa is 1150 L capacity (thus have gone with calcs on 1000L water)
Also I have the Taylor K-2106 kit.
Steps to date:
At Start:
TA = 10
pH = 7.4
CH = 20
TB = 0
I added 158g Sodium BiCarbonate ==> TA now 100
I added 144g Calcium Chloride ==> CH now 100
Ph = 8 (may be higher?). Not sure why changed?
I added 65g Sodium Bromide
Also added 80ml chlorine (12.5%) to shock
And some tabs in a floater
Let it sit for a couple of days:
TA = 125
pH = 8
CH = 125
TB = 1.25
Starting adding pH down (dry acid) eg. 14g, 14g, 14g, 25g, over a few days but pH would not budge.
Readings now
TA = 75
pH = 8
CH = 125
TB = 2.5
Have just added 44g Sodium BiCarbonate to increase TA.
Also the water is a bit cloudy (not sparkling clear like I have had in the past).
I have shocked the spa by adding chlorine and also cleaned the filters, but this has had minimal effect.
Any new ideas appreciated to return spa to ph of approx 7.5 and clear water
Thanks
