Title: Can't maintain Bromine level in new caldera tub
Post by: JimmyCT on October 30, 2016, 10:18:18 am

I'm in week 2 with a new tub and would appreciate any insight into water health. I have a caldera martinique (395 gallons) with an ozone system and inline spa frog bromine system.

I bought an electronic tester and have been monitoring/playing with the chemical levels for a couple of days. I'm using amerse spa care products as suggested by the dealer and came with the tub.
 
When I got home Thursday and tested the bromine levels were low 0.2
Ph was 7.8
Alkalinity was 87
Calcium Hardness was 134
 
I tried opening the bromine cartridge tab up to notch 6 and left it overnight and next morning down to zero. I used a shock/startup (1.5 oz Frog Jump Start packet) packet to bring it back up and also re-leveled the bromine cartridge back to notch 4. Within an hour the bromine level went back up to 7.8
 
Left this overnight and just re-tested this morning and it's the following:
Bromine: 0.0
Ph: 7.8
A: 86
CH: 134
 
Any tips on how to keep bromine level up? I know it should be above 0.5 with the ozone system
 
Thanks all

Have you tried additional shock?  Whether it be a non-chlorine shock like MPS or a chlorine based one, I would try and shock it to see if maybe your water has some issues that are eating through your bromine too fast.  I have a Marquis with the in line spa frog and went over a month on my first bromine cartridge with very little issues.  Like you, I used the startup packet and had my cartridge set to 5.  I had to turn it down to 3 to get the levels down.  Since then, it has been fine.

Also, check your cartridge to make sure the little openings are actually open and dispensing bromine.  Are you using a mineral cartridge as well?
