Good luck and post more pics!

Take a vitamin C tablet and hold it on the darkened areas - if you get a reaction the stain is likely metal.
Take a trichlor tablet and hold it/rub it on these same areas - if you get a reaction the stain is organic and shock levels of FC should fade these darkened areas.
whoozer said:I too am cleaning a swamp AND have metal staining. Right now I am still dealing with chlorine issues as my pool sat for 3 years so one problem at a time. When you get the FC under control, then come back and you'll be advised on how to help metal staining which is an entirely different issue. Note due to needing to remove metals at a low FC you cannot do both at the same time, so we wait
The first statement is very possible if you added your CYA through the skimmer to get caught into the filter, BUT you said 1) you measured 20 ppm CYA before you added more and 2) you measured 40 ppm CYA presumably sometime after you added the CYA. Once you measure the CYA, it should not get caught back into the filter so Leslie's would be wrong in this case.newpoolguy17 said:Leslie claims that I've cleaned all the CYA out (when I'm cleaning the filter) before it had a chance to set.
They also try to make a claim that clorox bleach is for clothes and it altered the chemicals in the pool making the CYA disappear.
frustratedpoolmom said:I would add enough CYA to reach 20ppm - I'm wondering if prior tests were incorrect?
No, the ammonia test is not hard to perform. I would go ahead and purchase one so we can confirm/rule out that this is what occurred, as it could also just be testing error...
newpoolguy17 said:Is it normal to have all this happening even though my pool is fairly clear?
If it turns out to be ammonia, bleach (and lots of it) will take care of it.chem geek said:Did your FC level ever get close to zero at any point in time (even for half a day)? If it did, then bacteria can grow in the pool and convert CYA into ammonia.
If the bacteria converted all of the CYA into ammonia, then that level would be around 12 ppm which is extremely high. In practice, the bacteria often have only some of the CYA converted and there are a lot of extra CYA fragments that don't measure as CYA nor as ammonia. So you usually have to add more chlorine than the ammonia test would indicate. As I wrote earlier, let's hope the bacteria didn't actually break down that much CYA.newpoolguy17 said:What kind of ammonia level do you think I would be seeing if the bacteria did eat 40ppm of CYA.
