Guess I'm just trying to figure out if it is REALLY needed to wait that long. My pool guy told me to spread it out around the perimeter of the pool. I was thinking about maybe doing half in front of one rturn jet and the other half in front the other return jet (I have 2 total).It is your pool and you will come up with your own routine. But that is certainly a safe recommendation.
Good advice, I'll pour a little and see how fast it sinks and adjust from there. I don't mind pouring slowly, just didn't want to if I didn't have to. Will it really mess up the plaster on the bottom of the pool even if its a small amount like 20 ounces?The faster you pour acid, more of the acid will sink to the bottom of the pool. With a slow pour over a return, more of the acid gets distributed through the water column. Watch to see how fast the acid is sinking when you add it and adjust as necessary.
It's always best to brush the pool to help distribute the acid and prevent any damage that can happen if the acid sunk to the bottom of the pool.
