im waiting for my chlorine to get down to 0. (at 1.5 right now) and i will be doing the absorbic acid treatment. i have a question as well. right now my PH is at 7.0... (AlK normal). is this an ok ph to do the treatment. im using natural chemistry products. Stain-Free and Metal-Free. the Stain-Free says to have Ph btwn 7.2 and 7.6. i dont want to raise the ph just for it to drop and have to raise it again.

I think it should be ok. We're talking only 24 hours after adding the products is when you begin to balance, so a low ph for that long should be fine.

Do not skip the algaecide addition of Polyquat 60. :)

You definitely want to use a polyquat based algaecide. They are fairly easy to find. Most products than have 60 in their name are polyquat based.

Re: polyquat 60 and absorbic acid before or after

To minimize the chances of getting algae, you want to add a polyquat based algaecide before the FC level goes to zero. If I am following your description correctly, that means not waiting till Monday.

Re: do i need more absorbic acid?

Everything is going fine, you just need more ascorbic acid. The older/thicker the stain the more ascorbic acid it takes to get it off. You are seeing lightening in some areas, so the procedure is working correctly, you just need some more. See if you can target further additions in the areas where the stains are worst.

I used the StainFree/MetalFree combo at several of my pools when I took over their operations. Some had green staining that had been building up for years.
The worst one, at 20,000 gallons (75,000 L) took five bottles of StainFree and a lot of elbow grease to completely remove the stains.

Depending on your pool's finish, consider using one of the pool brushes with the wire bristles rather than the softer ones. They can damage the finish (they tend to take off the paint in our concrete pools, and scratch the glazing on the tiles, if they are used too much), but in heavily stained areas they can help to lift it off more quickly.

Interestingly, I only have these green stains around the outside of the pools (floors only, not on walls), typically in shaded areas only, and they were only on indoor pools using SWGs. I wonder if the salt has something to do with it?
