Combined Chlorines

[xDom]

When I first got my pool, about a year ago ( before getting onto TFP ) I went through that patch of buying everything the pool shop would throw at me.
I have a full tub of this, Oxysheen

Oxysheen - Poolside

BioGuard Oxysheen is a chlorine-free, stabiliser-free oxidiser treatment for swimming pools. It is easy to use, fast dissolving and swimming can resume one hour after treatment.

I think it was sold to me to lower my chloramines at the time. It was then suggested to use regularly, weekly.

So, my questions are.. If I maintain my pool with the correct FC/CYA and there is never any abnormal bather load is it fair to say that CC's are not a problem and this product is not required.
also, even if my CC's were to exceed 0.5ppm then it could be combatted with raising the FC, so, also, this product is not required.

You are correct

It is mps -
Generally unnecessary in outdoor pools that are properly chlorinated.
It is only an oxidizer not a sanitizer.
Chlorine is both.
It contains sufates which aren’t good for your swcg among other things.

Problems sulfates can cause include:

• Sulfates can damage concrete & plaster
• Excess sulfates in water increases the likelihood of corrosion on metal parts
• Excess sulfates in splash out water leads to degradation of any concrete surfaces
• Sulfates degrade the coatings on SWG plates
• At high enough concentrations, sulfates can react with calcium to form spindly, needle-like crystals of calcium sulfate (gypsum)
• While sulfates in vinyl pools is typically not as problematic as in plaster pools, scaling of gypsum crystals can increase the risk of liner puncture.[10]

Sulfates can only be removed by draining water.

So what would be a legitimate use for this?

What is a "Tub"?

Sell it or give it away if you can’t return it.
Some people use it in indoor pools or hot tubs.
However, I have a hot tub & have never used it.
Its a known irritant.

That might be an Australian term, a bucket.
My “ tub “ is a kilogram.
