Yeah I’m noticing what maybe a few spots of calcium maybe. White chunks on walls, can’t brush off.
So pool shops are like anti virus software, they make the viruses to keep you coming back.

Yeah mate! We all could! Was like an albino cetacean. Truly magnificent.
The scrubbing lawdy LORD sweet baby jesus, oh the scrubbing. Not got the pig to stay on the end of my brush yet. But have located one for AM pick up.
So you know how my CYA is high. Is there some point in the chlorine vs cya battle where the chlorine wins? Like overwhelms the CYA? Or will it eat 5-10L a day no probs?
Slow dumping of pool water and replacement with tap continues 24/7. Lot of people screaming my name in the shower today, no idea why.

There's not really a magical threshold. It's just that let's say 95% of the chlorine attaches to CYA. It's protected from UV there, but has bugger all algae killing power even though it still shows up as FC in test.
What needs to be done is to make sure that the remaining 5% that are not attached to CYA are enough. That's why the FC level needs to be maintained the higher the CYA level is. At normal operation with a SWG no problem, even with up to CYA 90, the SWG just has to produce something like 2 or 3ppm of FC per day to maintain an FC level of let's say 9ppm. Easy.
The problem starts when algae gets a chance to sneak in, SLAM-FC for CYA 90 is just mental, hardly a chance.
Your best bet is to play the shower game until you get CYA below 50 or so. Just enjoy the squeales you get from diverting the cold water to the pool, away from the shower, and then back again. Sounds like lots of fun.
Heres a before and after for now. Same photo location in front of water suckerinerer. I reckon 60% of the pool was like this.
Edit: You can see the funny crack thing in both.

Yeah i found a few more muscles I didn't know about for sure. I reckon i'll keep at it for another week at least. Got my CYA back down now, so the chlorine demands will lessen. I know there's those 3 things you do at the end to know your SLAM is complete.
One tip from dads old mate who worked with pools previously was grab some straight powdered chlorine, turn off the pump, sprinkle all over and let sink before brushing that in. Sounded similar to the trichlor tablet rubbing I am due to do, but without getting the DTs on.
HOWD I DO BOYS PRETTY GOOD YEAH (for now) ?!?
At the pool shop today and this little old lady was having issues. I was able to answer her queries better than the girl running it that day for the normal bloke. Great for me, embarrassing for her. Also ordered another test kit for my brother and his new house and pool. He'll never have to go through this algae Darn like I did.
Edit: fk I love pool math.

Sounds like Dads old mate is referring to dichlor. Basically similar chlorine in your puck but granular. Like a car same make but different model - both add CYA to your pool water. You had me cracking up at “water suckerinerer”. Sounds like a technical Aussie industry term
. Carry on!

Either that, or cal-hypo. In both cases: A little is OK, just important to be aware of the side effects. PoolMath's "effects of adding" will show how much CYA a Dichlor addition, and how much CH a cal-hypo addition will add as a side effect of the intended FC increase.
Golden Rule of TFP: Know what you add, including the side effects. PoolMath is your friend.
And a warning: Never mix different types of chlorine. It's OK to add them one after the other to the pool, but never put the rest of your old tub of chlorine into the new tub. If one is dichlor and the other cal-hypo then this will create an explosion.
My buddy blew up an old bucket that he thought was clean. I forget now which was added to which but the bucket had been rinsed so he thought it was fine. 5 mins later it blew apart leaving a 5 gallon bucket sized divot in the yard. His cameras caught it and the blast zone was about the size of a garbage can (10X the original size), from only a little residue that he couldnt even see. Had he still been nearby he would have been hit with shrapnel or sprayed/burned with chemicals. It was a good thing he was busy doing a bunch of things in the yard and walked away from it.

FYI... there is no such thing as "straight powdered chlorine" or solid chlorine. If only there was, our lives would be so much easier and more convenient. But that has yet to be invented. No, chlorine must be bound to something else for it to take on it's evil solid form! For the most part, that is either CYA or calcium. So adding any form of "solid chlorine" (or powdered) to your pool water is also going to add something else. And something else that doesn't just "go away" when the chlorine does.
That's why we teach what we teach about liquid chlorine, and that the use of pucks (in general) is not a sustainable method of pool water maintenance, because it will eventually end up maxing out something you don't want too much of in your pool, and then you have to drain your pool and start over, only to repeat this wasteful cycle over and over and over (which is exactly what most non-TFPers have to do).
It's why so many of us rave about our salt water chlorine generators. Better than the convenience of pucks, but nothing added except the freshest chlorine.
Told ya so. And here you are, already teaching others, at the pool store no less!!

This looks a lot like copper stains.
Copper usually starts out as turquoise and then begins to turn black.
You probably also have black algae as well, which makes it harder to diagnose the problems individually.
Most likely, the copper was added as a treatment for the black algae.
