Bromine Salt Corrosivity

Bromine generator requires less attention then what?

What bromine generator are you thinking of using?

NaBr salts should be less then 2,000 ppm which is not a high salt concentration to be very corrosive.

What will you have in your spa that you are concerned can corrode?

Bromine generators seem to be built for spas of around 500 gallons. Do you have one that can generate sufficient bromine for your 2,400 gallons?

I have read that a salt water pool could shorten the life of the equipment (heater, pump, other metal fixtures in the area) similar to living by the beach.

You did not read that here. There are loads of us who have "salt water pools" with no problems.

The salinity in a salt water pool is around 3,000 - 4,000 ppm. The salinity of ocean water is 10X that, around 30,000 ppm. It is a false comparison to compare the two and say they have equal corrosion possibilities.

Study the materials in pool equipment and you will find the water is not in contact with any corrosive materials in pool equipment. The pool equipment companies sell the SWG's. They would not sell equipment that damages other of their equipment.

I did not know if there was a difference in the corrosive nature of a salt water pool as compared to a bromine pool that uses a generator vs tablets.

Salt is salt. Whether is NaBr or NaCl.

And the dirty little secret is the tablets probably contain salt that is being added to your pool anyway.

The whole issue of salt and corrosion is a red herring repeated by people who don't understand the chemistry or materials involved.

I have not spec'd out a system yet, but I have read that some people do use this system on a pools.

You need to identify the specific models you are thinking of to have a discussion on the pros and cons for the spa you are building.

One is with a tablet systems that you need to monitor and keep filling, and one is by establishing a base with bromine salt and then using a generator to release the bromine.

Bromine works one way. There are a few methods, but they all do the same thing. Sodium bromide is added to create a "bank" or "reserve" and an oxidizer converts sodium bromide into bromine. The most common oxidizer to use is chlorine, which is the main ingredient in a "bromine" tablet.
Generators can have issues and expenses. The chlorine ones can result in very high ph, which causes scale. Scale can cause a lot of damage to equipment and is not covered by warranty. I have personally seen a gas heater clog up and catch the plastic parts on fire, and I mean that literally, in under 6 months from issues caused by chlorine generation and an uninformed owner. It also melted the siding on the house but (luckily) did not catch the house on fire. Raypak flat out refused to warranty the heater or cover any damages, stating that this damage was the result of chemical neglect and use of a salt cell. The exchanger tubes were full of scale, by which I mean the pipes were clogged with limestone, and the safety devices were rendered useless by being buried in it.
I have no experience with bromine generation. There is some question as to it's safety and it has been banned in certain places, including Canada. I do not know the details on that.

You can call it a spa, I would call what you are building a plunge pool and treat it as such.
