I had the same problem as you and the same experience with trying to identify the stain and treat it. Eventually, I gave up and called in a couple of different local pool guys. One suggested a full drain acid wash and the other was a no drain acid wash for 3-5 days with the existing pool...

Not sure if this requires a new thread but essentially I have the same issue as I did last year as the stains have returned. I am at my wits end as what to try to get rid of these and prevent these recurring. I think I have read so many threads on here I have confused myself between organic...

77 last night in Austin. Will be a large hot tub soon enough..

Thanks also from me as I am going to try this. A couple of questions however, as my pool is plaster, what extra care should I take versus this wash on pebble/plaster? What is the target pH? Thanks, Stuart

Scott, Thanks for the input. After some dilution I have retested and this is where I am now: FC 7 PH 7.5 CC 0 TA 100 CH 290 CYA 90 My pool does get 10+ hrs of direct sunlight. Am I correct in thinking my CYA should be in the range of 60-80? Current water temp is 67. I am still working on...

I retested today and my PH and TA seem to have dropped quite a bit. New results are: FC 9 PH 7.2 CC 0 TA 110 CH 300 CYA 100 I am now working to replace water to reduce CYA. What would the next step be? I have noticed a product called Scaletec, would this be any use in removing the stains...

Thanks Jason, I am working on lowering my TA as I admit I must have let it and my PH drift. How quickly would you expect TA to drop? Is it possible to drop by 50 in a matter of days? I ask as I measured 180 on Thursday and have got to 130 this morning. I have been keeping my PH in the 7.2...

Thanks guys for your feedback. Just received my test kit today so after a few attempts here are the numbers: FC 13 PH 7.6 CC 0 TA 180 CH 300 CYA 100 I tried to take a picture but it is still quite bright outside and although it looks like the same pattern & detail as above too the naked eye...

Split off of this topic. JasonLion Hello all, I am newbie here and not trying to highjack this tread but have recently came across the same issue with my pool surface in the last few weeks. I am trying to stop it in it's tracks before it gets out of hand. Can you provide any update on how...
