I am having a few spots repaired where rebar ties have rusted/bleed through the plaster. After the spots have been patched would I go about starting up my pool just as if it had a full replaster? Also, on the startup sections I didn't come across a step by step process on starting up with new water. I know ph is very important but I didn't find a method that introduced chlorine to the water. Btw i have a 20,000 gal gunite pool that is about 7 years old with a SWG. Second owner. Any info is greatly appreciated...thanks.
