Sodium bisulfate question

[Bam Bam]

I’ve read many posts that say do not use sodium bisulfate in swcg pools. I can’t find a similar warning for non swcg pools. Any reasons why muriatic acid is preferable from a pool integrity point of view?

Thanks!

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.

Thanks Allen. Those are convincing reasons to avoid.
