What is the effect of phosphorus in saltwater on electrolyzers? (Urgent help)

I am referring to the solubles of phosphites and pyrophosphates
I’ve never heard of this thing before, but I think it should cause the rail voltage to rise!
I think phosphites and pyrophosphates may undergo redox reactions with hypochlorite at the anode of the electrolyzer, resulting in the formation of phosphates and chloride ions, which reduces current efficiency. The solubility product of calcium phosphate is 2.07*10^-33; if there are 20–30 ppb of calcium ions in the electrolyzer, calcium phosphate precipitates will form and adhere to the surface of the membrane, thereby blocking its pores. I’m not sure if this reasoning is correct – I would appreciate some guidance from those with more experience
