A work associate is performing a "hot start" or "hot start up" procedure on a pool. He lowers the pH very low to treat the plaster, and then raises the pH to acceptable levels. He wants to use Sodium Bicarbonate first, then Sodium Carbonate. I'm trying to tell him that when he's all done his total alkalinity levels will be way too high and the water will have high pH problems for weeks or months because of this.TA itself is a source of rising pH due to carbon dioxide outgassing
Can you tell me more about how Sodium Bicarbonate leads to Carbon Dioxide outgassing?
