No actually I think that's spot on. For low ph you add air.
Hey does the tank smell? No missing animals.
Then it's a cyano or spirulina.
You should siphon and clean that spot.
It makes so little sense to me it would only be there and nowhere else in the tank.
I assume your return hits that spot?
What kind of filtration do you run
I prefer an oppsite time sched. Seems better to me. Each thank apirates the opposite Gas when the light is on or off.
But no. It shouldn't have any effect.
This seem a larger prob like an addition in water or a food source. Like a dead thing.
IMO the dead thing can sometimes be sand and rock if the bacteria get killed. Bleach for example. That's one worry in tap water. Bleach and other compounds. Depending on where you are it's fine to use. At my house it will kill a tank.
In the tank pic. It looks like there are spots on the back wall of corraline. Do they look purple and healthy?
Also no missing animals and it doesn't smell. It started to grow pretty much after I set up the tank first I notice bubbles coming from the rock then it started turning green and then the pink grew on top.
Geez. It would almost be with taking the rock out and putting it in a bucket with a powerhead to test the Po in there.
I have to believe there's something nasty in the rock. No idea how it happened

This is a stupid question. In the pic ther is a detergent can. Do you use that? Are you near the laundry ?

You should be checking the PO after removing all of the algea possible and doing a water change. High phosphates can lead to this type of bad algea growth.
Have you added anything to your tank recently...sand, rock, etc?

I'm stumped. Po that high and only a few spots of funk.
Not worried about ph at all. Interesting that it's perfect ph.
None of the test kits have expired? We checked it twice.

How much light on the tank? (Do you have any kind of light meter?)
Did I read tat this tank is 6 months old?
Let me make sure I have this right by summarizing....correct anything I get wrong please:
40 ppm nitrates
2 ppm phosphates
8.8 pH
Something in there was alive, is dead and now dissolving slowly into your several gallons of saltwater.
The light is in heavy agreement with cyano over this and is steadily using up all the CO2 in your water trying to clean things up.
The crazy colors are either from very intense lighting or straight-up just the crazy-high nutrients. Or maybe even from the high pH being generated by the heavy CO2 consumption.
The skirts on those polyps being all tucked under is a little weird too.....too much light?

+1 to this
Looks like two different types of cyano with some bright green film algae? Kind of pretty.
Because the zoa polyps skirt is tucked under, rather than closed up(in relation to high light), makes me think this rock was recently moved to the top of the tank. The long stalks would suggest they were in lower light and were moved up for more light. Now this rock has weird stuff growing? I wonder if this isn't the result of some type of organism cooking? Something encrusting like a sponge or tunicate? Just a thought.

I thought it was sponge ore something and was feeding on silicates and Po an bacteria. Notice no other funk in the tank.
Back on my 30 rebuild the cyano clung only to the high Po rock and sand. Or I'm a nut.
So wit it hitting only really that spot I t makes me thing that's where the return is dropping food or the rock has a weird nasty in it.
Despit the higher flow claims I've always seen cyano where the flow ends from the return or movement and large collections there. Think Like a hose in the back yard kinda.
Or on a surface with extra food.
