I am planning on having my pool completely drained and acid washed. The pool is about 6 years old, it has some light white staining on the bottom and some surface calcium scaling - hardness 700 , high CYA and high TDS.
I'll have a local neighborhood pro doing this for me, but still little nervous about it, so I want to ensure everything is handled correctly.
My questions are:
What is the correct process to follow during the acid wash? The pro mentioned he will mix acid/water, brush the walls and bottom and rince all with pressure muzzle attached to a water house.
Is a power wash needed as final step?
Is any polishing involved?
How many bags of salt do I need initially for an Autopilot SWG setup.?
Ather suggestions to keep in mind?
Lap shape pool approx 40k gallons located in Phoenix metro.
Thank you all in advance for the advice.
