    Need help BAD! ***pics***

    1st thank you for reading... I have a bad black algae problem in my pool, I just tried to pressure wash it, pool is drained, but it had zero effect on the algae. I have mixed a chlorine paste to wipe on the side of the walls over the black algae spots. This seems to help reduce the color but also kind of turns my plaster blue. Im not sure what to do at this point... my pool was just acid washed in March and hasnt had a problem I have seen since Ive owned the house 2.5 years ago... Im in AZ pools about 10-15,000 in ground w/sand filter

    Any thoughts on what I can do?

    Can you post some pictures of the spots? It doesn't sound like black algae to me.

    Have you used algaecide or "sanitizer" containing copper?

    Re: Need help BAD!

    i can but right now they are covered in chlorine, The spots are a very dark green... I had lots of trouble with the pool vac this year and my water got trashed, so then i drained and acid washed, I dont think I kept the water levels correct and generally just exhibited neglect, lots of trips ect... its not slimy like most post say BA should be, its rough but my plaster is on the way out i believe... overall the pool is rough to the touch. The more I neglected the pool the more spots would show up scattered around the pool. The chlorine rub right now is helping with the color but also turning my plaster blue... after I wash it off in the morning i will snap some photos, i wish i thought to do that before...

    Thanks will the help ; )

    Re: Need help BAD!

    It sounds like metal staining. Try getting some vitamin C tablets and holding one of them on the spots. It'll have to be wet of course. If that lightens it it's metals.

    Re: Need help BAD!

    I agree with Bama, especially as the chlorine is turning it blue. Sounds like copper staining. Back to the acid wash and locate where possibly the copper came from

    Re: Need help BAD!

    Really, you think I need to do another acid wash? how come I could get the stains to go away with trichlor and then they would come back?

    Re: Need help BAD!

    Ok so here are some images, you will see the blue discoloration from the chlorine wash (im guessing this will gradually go away when the pool is refilled or hoping!) the stains where all dark dark green and now have faded to a light grayish tone.

    Well, I'm gonna muddy up the water a little and say it looks like calcium scale to me. Usually created by high pH or Calcium over a long period of time.

    Keep in mind these stains (you all have me guessing) where really dark green.

    Any thoughts on what my next step should be?

    Spray some diluted muriatic acid on it. To me, it looks like your pool plaster is blue, and you have a coating of white scale over almost the whole surface. What was your "chlorine paste" made of? If it was made of trichlor or dichlor, they are acidic and could have dissolved some of that white coating.

    If calcium scale gets stained, the color will be embedded in the scale and can't be removed unless the scale is. Your plaster is definitely on the way out, I can see a delamination right on the edge of the shelf in your last picture.

    Scotts/PHX line... Yea I was told the plaster was on it last layer ; ( after my acid wash in March... Now if you are saying that my entire pool is coated in Cal Scale that's crazy and hard to comprehend! g'z that would be terrible... the pool is almost marbleized with blue faint blue lines on the white (i thought this was from the chemicals i was dumping into the water)... but obviously the Chlorine Paste I made turned the areas blue where is was spread...

    here are the chems i use

    Paste (i made) (and would use as shock for the pool)

    Re: Need help BAD! ***pics***

    Ok so I did some more work, lil power washing seems as tho the water got those blue stains dissolved and I used a 50/50 Acid on some areas where the stains where more stubborn, but mostly water did the trick... Now here are some shots of the plaster and whats left of the stains... the stains are now solid grayish white, Im not sure where to go from here but the pool looks much much better, the plaster is overall aqua in tone with some areas of a brighter white.

    Nice work. The pool doesn't look too bad. If you want to pursue it further, you might try a 3:1 dilution of muriatic acid directly on an inconspicuous stain. If it foams up, it is likely removing calcium scale.

    While calcium is not green, algae can thrive in calcium scale and discolor it from green to brown. That may be what happened in your case.

    Now, that said, understand that everyone is guessing as to what may be wrong but there is one thing for sure.....to prevent it from happening again, you will have to manage your pool chemistry better. There's lot's of articles in Pool School and this forum will help you as much as you want. Tossing stuff in your pool without careful dosing and testing will lead you right back to the same conditions you are now getting cleared up.

    I will give that a shot along with a little sun, then i'm going to fill her up, read about this BBB thing and get a solid test kit. Any recommendations? I did use a lil CLR on a spot it foamed up nicely but didnt really remove anything, I didnt leave it on for too long because I dont know what kind of effects it might have on the plaster... but it does look calcified to my eye, and had me thinking whatever algae it was may have lived on top of the calcium... ect... tough to say because im by far no pool expert!

    Just go to http://www.tftestkits.net and get the TF-100. It's a good buy and the best test kit out there for a pool owner. Go ahead and order a speedstir while you're at it. You won't regret it, especially when you're running that calcium hardness test!
