Great forum and I have tried to read everything and learn before posting. I have a Hot Spring Spa of about 500 gallons. I am trying to use the Bromine system as described here. I used the sodium bromide when filling to get the bromine bank. I am also using a floated and using bleach as a shock. TA and Ph are in balance, but my bromine levels go very low. I purchased the Taylor test kit and have religiously been testing.
Does it make sense my bromine level falls to around 1? How do I get it back to the target of 3?
Thanks for all the great information available in this forum.
