(Reposted into new thread due to no response)
I have a question about my current SLAM.
I'm on Day 11 and still losing chlorine - I believe due to a build up on the walls that I just can't get off. I have manually skimmed daily and brushed the entire pool multiple times daily. (in addition to cleaning the filter every day - I have 2 brand new filters that I swap out/clean daily).
My dilemma is that I just can't get the stuff off the walls to budge! It is hard and rough - feels like concrete on my (used to be) smooth fiberglass wall. On day one it cut my fingers when I tried to rub it off! It's not as rough today.
I tried pouring a tiny bit of muriatic acid on the edge and it did bubble, but didn't seem to come off.
Is there something I can do during the SLAM process to loosen this stuff off the walls? Or do I have to wait until I'm done with SLAM?
I'm making progress, but still not there yet. I get so exhausted brushing trying to get it to budge - this 'ole girl just needs a little help!
I've retested my CYA again this am and it's currently sitting at around 45... so I rounded up to 50 for PoolMath.
You can barely see the build up and streaks on the wall in the pic, but it's extremely noticeable in person.
Pics in order:
1) Day 9 build up on walls
2) Day 1
3) Day 5
4) Day 6
5) Day 9
