    Black & Blue Stains on White Plaster

    Hello kind members, I have a white plaster pool that has developed black stains, mild blue stains, and a couple of yellow stains. After loads of reading, I'm thinking these are all metal stains and I'm planning on using the Jandy Stain Master to apply a modified no-drain acid wash to the entire...

    Recurring Metal Staining

    Metal Staining is returning mid August, 3-4 months after the May AA treatment. I knew this would happen. I’m going to have to accept that an annual AA treatment is necessary. Here is why: Iron and other metals are found in gas and Diesel engine exhaust, as well as in road grit...

    Organic staining in spillover spa

    Our pool has had significant stains in the spillover spa since we purchased the home and accompanying pool 2 years ago. I paid very little attention to he spa, since we almost never use it. I assumed that it was mineral staining, but none of the stain testing made any change so I let it be. By...

    Rebar Stain

    I'm having a pool built in my back yard and I noticed what looks like a rebar stain on the side (see pics, below) Do you think this might cause a problem? The pool still needs decking and plaster. The builder started on this pool back in November of last year and is still at it on and off...

    Brown Stain

    Our aqua blue Pebblesheen is 3 months old and I’ve been diligent with taking care of it. This morning I found a brown rust looking stain in our deep end. I did add some calcium chloride yesterday add my CH level had dropped with the rain we’ve had. Could that have caused it? It won’t brush out...

    This spring I will finally conquer this stain

    Since getting the house, I have had a large stain in the bottom of my gunite pool. It is large and kind of cloud shaped and dark brown. The stain has not changed size or color over the years except where I have attempted to treat said stain. Previous owners did not do a good job of maintaining...

    Stains and Mottling On Plaster - Remove and Prevent

    Hello all, We're getting quotes for tile/coping work to fix some issues on an older (late 80's maybe) Anthony and Sylvan plaster pool. While doing that, we're trying to make the rest of it as perfect as possible. We have some staining and then some off-color mottling all over. Three questions...

    Help removing stain

    Hi everyone, just opened my pool a few days ago, and I noticed a lot of staining on the floor, sides, and steps of the pool. It was resurfaced with diamond brite last July, and was fine at closing. I scrubbed with a brush, vacuumed, etc and nothing could get the stain out. Just tested the water...

    Suggestions for using Jack's Magic Copper and Scale

    Recently bought a house and it came with a pool. It wasnt kept up for a month or two, and it started to go green. So I shocked it and put in algaecide (maybe did this twice, and used 6-1 chlorinating tabs in between), and it seemed like the last time I did it the next day or two a really bad...

    Mystery stains on liner

    Hi all, I'm stumped on this one. So this little patch of yellow/brown stain appeared towards the end of last season. Can't brush it off, looks like a stain but thought it might be organic so I SLAMmed. I worked hard to keep FC greater than 30 ppm for a few weeks but the stain remained, and it...
