Well Water: Why you DON'T shock BEFORE using Sequestering Agent

[mbar]

A ph of 7.8 with an alkalinity of 130 plus high chlorine is what will make the metals fall out of solution. A water softener will make the water more alkaline, but should also help to take metals out of the water, but it is not getting all of it out. You will have to keep sequestering agent in the water to keep the metals that are getting in tied up. I add water from a well also. I like to keep my ph no higher than 7.6, and my alk around 100. When I add water I drop my ph down to 7.2, and put a trichlor puck in the skimmer. You can do this with a sand or DE filter - NOT a cartridge filter. This way if there isn't enough sequesterant in the water, the stain should fall on the filter first. Sometimes lowering the ph and adding sequesterant will take the stains off the pool, if they are not to embedded. Since the stains are on the steps only, you can also try putting some ph down in a sock and rubbing it on the stains. Hope this helps, feel free to ask any questions you may have.

that is exactly what my pool looks like. What was the name of the sequestering agent that you used? I have a 14000 gallon AG pool. I am postitive that you took a pic of my pool.

Sequasol, or Jack's Magic, Metal free are all good, they are the one's I have tried so far.

I think it is - I never used it, but as long as it is a sequestering agent, it should be ok.
