    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...

    Cloudy water; stained liner

    Hi, It’s been awhile since I’ve been on here. I’m coming out from a huge Algae In my pool. I have finally got it cleaned up from that (I hope) and the water looks fair - is not crystal clear. I just tested and I have CC 2, FC 8.5, TOtal C 10.5, Alk 70, CH 125 and CYA 40. Is it just gonna take...

    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...

    Pool stain

    Hello, I'm new to owning a pool and have frequented this forum for maintaining the pool after having an algae breakout. I've gotten a test kit and been trying to keep the right levels.

    Imaginary iron in pool?

    Hello, everyone. I've been lurking around the forums for some time now, and while I've gathered a lot of good information, I'm still struggling with my pool this year (2nd year of owning it). I'm cursed with the iron staining problem, and I feel like the pool store is just milking my wallet. My...

    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...

    Chlorine before Yellow Out

    Hi all, Thanks for the forum.......really appreciate the ability to ask questions here. Have two issues but will start with this one. When I first bought the house (with the pool and spa) it has mustard algae and yellow out did the trick extremely well. This year I didn't know I had water...

    Hello! I moved to a house in northern California 5 months ago with a pool that I think is at least 16 years old. I've been learning a lot thanks to TFP and the water looks great, I test it all the time and take it to the pool store weekly. But the pool has had these stains near the main drain...

    Hello guys, need some help. I just got my new pool installed. It was filled with water about a week ago. Immediately after filling with water I noticed 3 problems. One was a "bare spot" on one of the steps where you can only see plaster and no pebble. The second is similar bare spots on the...
