    Black lines from main drain

    Thank you for all your guidance Rancho. Much appreciated. I just put in some stain remover a few hours ago and don’t see my change but I guess this is more of a process and will have to apply it regularly over the next few weeks. One of my challenges is these are not new stains so it may be...

    Never used dry acid In my pool - only used muriatic acid. I only added muriatic acid today because I was adding the stain remover and we have to bring the ph level down before applying the stain remover.

    I agree. One of the things they said to me today is to get a good stain remover (which I just got) apply the full bottle initially around the pool with the focus on where the stains are and then apply a little of it each week. I am not a huge fan of using acid in my pool either but when you have...

    Ok just got a call from the pool company that was just out there. They think it is scale from the plaster that was installed when they did the resurfacing. They did recommend to add acid weekly when they completed the resurface and I did that but I have not been adding any acid over the last few...

    We got a new heat pump when we had the resurfacing done. We had no heater before that. Can the heat pump cause iron/copper issues with your pool water? Last night I tested chlorine, ph, alkalinity using my test kit and the results were fine. I’m not sure if these would test for metals. Based on...

    Will do. I can do that this evening. What exactly am I testing with the test kit? I ran tests last evening with my kit and everything seemed ok.

    No, they run from or near the main drain for about 4 or 5 feet but they not on the walls where the returns are. The pool company that did the resurfacing are coming out today to have a look. They had recommended to put 3 gallons of acid and brush and brush. I put one gallon of acid in the pool...

    There was definitely nothing for at least 6 months after the resurface. I think initially they may have just been 1 or 2 streaks now their are about 4 or 5. They are light so some people would not even notice if you were not aware of it. I will take some updated pics in a few minutes when it get...

    Black lines from main drain

    Thank you Rancho. Where I am mystified is how can these lines/stains be so structured. I will take a pic in an hour or so when it gets dark. It almost looks like a spider web all originating from the main drain. I do have a test kit, I will run some tests. I just tested the ph level. Now it very...

    Black lines from main drain

    I did just speak to the company that did the resurfacing. He does not believe it is rebar stains. I did run a chemical test and my ph level was high so I just went to the pool store and got some muraitic acid (the company thinks the stains have something to do with high ph level?) so I just put...

    Yes you are correct. It is auto suction cleaner that I have connected to the drain on the side of the pool and kicks on.when my pump comes on. I will take a pic later when it gets dark with the pool light on.

    I normally powder shock or liquid chlorine The pool resurfacing was done in Apr 2002. We also had a heat pump installed with the resurfacing. I hope and pray I am wrong, but I hoping these are not rebar stains from the resurfacing. As I said I have only noticed about 6 months ago. It has not...

    The lines are there but I guess it is difficult in daylight with the glare. I will try and take more pic later when there is less glare and I can put the pool light on. Almost looks like half a spider web and everything is originating from the drain.
