Hello All,
I've recently started maintaining my SPA (approximately 400 gallons) and recently "upgraded" from test strips to this test kit:
http://www.amazon.com/gp/product/B00107039U/
It has been a nice improvement, but I am still getting used to it and the instructions do leave a bit to be desired.
This past weekend, I checked Bromine level and it was quite low, so I added approximately 110 grams (~4oz).
I know, it's too much, but in my defense The test-Kit's instructions don't mention how much bromine or chlorine to add, when needed.
I also checked Acid demand, and based on the chart, it said it needed approximately 1oz (3 drops of "acid demand" solution brought colour to down to expected level)... which I added (muriatic acid).
I checked again a few days later, and the Bromine level is high (as expected due to my error), but the Acid Demand skyrocketed too!
I dropped twentyfive (25!) drops of "acid demand" solution and the color was still unchanged (normally 3-4 drops are all that I ever needed).
I stopped at 25, not wanting to waste the entire bottle.
Could you please advise me on what to do next? I suspect the Bromine level has dropped by now, since it's been almost a week.
Also, one more piece of data: I've used this test kit 4-5 times so far, and everytime it seems like I need to add about 1oz of Acid, so I've been adding about 1oz of muriatic acid to it every week.
Thank you in advance for your help!
