Huh,
I never contemplated it could be both. Years ago dad dumped copper in, in an attempt to control early algae I assume.
Would those stains dissipate in a similar way to mine from high FC and backbreaking scrubbing?
So pool shops are like anti virus software, they make the viruses to keep you coming back.

Didn’t think so, hence why I came home empty handed after checking the backs of the packs the pool shop chick handed me.
Cheers.
Drop a vitamin C tablet on a few spots to see if there is a reaction.
We're not allowed them. Mum says have a bloody orange. I'm guessing popping an orange on there won't work the same.
It might if it didnt get too diluted. I used orange juice in my Kureg coffee maker to get rid of the iron stains in the water reservoir.

Stupid Pool Tricks
DIFFUSION! Your using your pool light like one big CYA turbidity test! Nicely done I deleted a bunch of my SLAM pics after moving. I had a good one of the pool light as a 2 foot wide Light-Sabre blazing across the cloudy water, like high beams in the fog. turbidity That’s a big word...

BLOODY GOTCHAS
It's nice you assumed i'm just a lil slow so acted professionally the whole time. Cheers. @Newdude imma try that for my coffee machine too.
Vitamin C's on the list @JamesW ! Stuff mum.
I found something else, a 'metal magic sponge test' linked to in the wiki:

But the link is dead. Should I tell someone about that?

Haven't got vitamin C yet, have got the all clear (supposedly) on copper using my new, non franchise, dude in an industrial unit, selling cheap chems, and cheaper chemicals, pool shop. He could be dodgy like many, but at least he's not pretending not to be. I'm reassured.
Check my pool math log if interested. My chlorinator had stopped this arvo saying low salt. Weird cause it was 4k this morning on my drop test. The pool shops conductivity test says 3080.

Do your SWG plates look scaled up?
Did you add lots of that powdered chlorine, and was the SWG running while doing so?
Usually we prefer to keep the SWG off during a SLAM anyway.
The copper test tells you that currently there is no copper dissolved in the water. Copper that came out of solution and settled on pool surfaces would not show up in the test. This may have been copper that was in the water a long time ago.
The fingernail test showed that you definitely had black algae, and also that you were able to improve it by slamming and brushing. But there still may be copper in there. Do you have a current picture?

Generator plates look like a few percent scaled up. Nowhere (1/10-20th) near old days. Will hydrochloride them asap to rule out.
Purchased no powdered chlorine. SWG been off all week. Had on first 72 hours maybe before realising.
Good point re copper, maybe stained long ago. 100% was algae at least.
Will grab photo first thing of the remaining darkest spot.
Nb: I’m getting funky salt reading from my CCL salt tests. I tested reference water included at 5400 and again >4000 but ran out of reagent. I got more reagents en route.

Try to avoid using hydrochloric acid. Even though that's what the manufacturer recommends, it's not great for the cell. It takes some of the plate coating off, reducing the lifetime.
Try first if you can push some scale off with an icy pole stick or similar or using a garden hose. Next step cleaning vinegar. Pool acid should only be the last resort.
Increase the salt maybe up a bit, the Astral Virons operate usually best between 4000 and 5000. They are OK with up to 8000. When the plates get older they start mucking up with the low salt reading, in my old unit it was basically on permanently, just ignored it. In my case it was still producing. Maybe add around 500ppm or so.
Especially if your salt standard (I think it should be 4000ppm, right?) reads 5400. If the pool reads 4000ppm, it might actually be lower. Send CCL an email about that, something seems dodgy.

This is true for cleaning just about anything: start with the least corrosive/invasive solution first, work your way worse.
Be gentle with any mechanical cleaning. The coatings on the plates are what make the magic, and they can be scraped off without much effort. Don't use anything metal, for sure.
If only I'd got this advice in my teens maybe I wouldn't look like two-face but without the nice side or an acid attack victim.
'Starting with the most corrosive' I just called "exfoliating".
I imagine i would've somehow exploded my pool by this point without all your guidance EVERYONE in here! Thanks.

That's a thing. The previous owners of my pool, and then I, didn't know the first thing about taking care of one. It hurt my skin and eyes, it had algae almost every week, the entire finish was covered in calcium deposits, and eventually I had to have the whole thing redone. It got all chipped out and looked not too different from an explosion.
Finding TFP has kept my new finish looking that way, and like you, I'm grateful for stumbling on to this site. Just keep in mind, we don't know anything more about pools than you're going to, we just happened to learn it here at TFP a little sooner.
It got way worse when I started using the pressure washer!
Do I call the police or protec my dead dad ?!?

Question: With my FC test unavailable due to foreseeable overuse how much chlorine shall I dump in daily? SWG can go back on prolly.
1/2 gallon of 10% is 3.8 FC if we guessed the 50k litres right.
Well I’ve answered the question of whether we live in a simulation.
Don’t care how advanced our creators would need be. There is no amount of GPUs that could simulate that number of particles. I just flushed out more Crud than there are stars in the universe easily.
