They told me to exchange water by draining by putting the pump on the first step and draining to the step and refilling. We need to redo the process multiple times. They recommended for decreasing cyr level
Are you new to the property?
Can you show the system?
Can you post all chemistry readings?
You can add water and drain at the same time at an equal flow rate so that the water level stays consistent.

I will post them as soon as I do a new reading. We are new and the pool is 70 years old. It has sand filter. I will post pictures
The two main copper stains are turquoise and gray to black.
Turquoise stains usually happen first.
The turquoise gets turned black by chlorine, especially by calcium hypochlorite.

Copper can come from a heater, algaecide, some chlorine tabs contain copper, ionizers, mineral cartridges etc.
They put chlorine tablet on floaters and we just replaced the heater since the previous one was lesking
The heater contributed to the copper levels.
The water chemistry was probably bad (low pH etc.) and the tabs were probably used in the skimmer or a feeder, which can corrode the copper heat exchanger in a heater.
They might have added copper algaecide or used other types of copper as well.
Do you think that I will be able to solve the issue by exchanging the water and using Home / Stain Program / STAIN SOLUTION #2 – The Copper & Scale Stuff?
Possibly.
You have to take the heater out of the system during the treatment because the treatment dissolves copper.

Should I add the chemical when the pump is off and mix it by brushing or vacuuming?
