Sodium Bromide Dosage

[cschnurr]

Can someone reconcile these two instructions.

My tub manual lists the size as 1350 litres and recommends an Initial Bromine bank of 3 litres of Sodium Bromide.
It does not specify the strength.

The thread below recommends a dosage of 125ml of 35% Sodium Bromide per 1000 litres of water

Liquid Sodium Bromide

Hello, I'm looking to establish my first bromide reserve in my hot tub. I was not able to locate any granular form of it locally. The only thing i was able to find is in liquid at a concentration of 35% of Sodium Bromide. Instructions say to add 125ml(4oz) per 1000Liters(264gal). Does this...

Which would require 170ml, which is about 1/20th of the hot tub recommendation.

Thanks

I can't speak directly to the issue since I'm not familiar with liquid sodium bromide, but I would follow the directions on the label of the bromide. For a bromide bank you can't really overshoot it, any amount over the amount you are using as bromine will remain as inactive bromide. So if you're concerned don't be afraid to overshoot the instructions.
