Results of my fish tanks after nearly no operation for 1 and a half months

So the parameters, I thought it would be something like ammonia and then the test explodes because of 9999999ppm ammonia but actually...
Everything was super clean, like I've never had such good parameters of NO2 no3 and other nitrogen things, but I haven't tested calcium, KH and other, there's a lot of algae, my crabs died but them immortal nassarius are still alive, they were... Skinny, weird
In my freshwater no3 is almost at 0 ppm, and I know why this happened but don't know how to explain it, but I'm still shocked
The anemones were skinny to because I turned off feeding, it gave like millions of pellets which caused some of my crabs to die, but I fed them and noticed that they gave birth to a lot of tiny nems
For some reason everything is suffering the most in the warm saltwater tank, even AIPTASIA DIED what the heck? but it's the cleanest tank I have

40% of the coralline has died and the plants too, luckily there's some coralline on the glass in the back (not talking about that big brown algae)

this one looks crazy but the crazy thing is that it has the most survivors, nothing died

that looked so beautiful but I had to throw them away since they grow so fast and cover the light, causing my plants to die

Also, a month ago I did a post asking what should I keep and what should I get rid of, I kinda want both of them but I only can get rid of the cold saltwater tank, it's a 2 hour ride to the place with the same water temperature, conditions and everything

You said;" Even AIPTASIA DIED. "

That is not possible. They are immortal and grow without food or light once they are in a tank.
Otherwise, do you have a peppermint shrimp or some crab that ate them? (It should also be immortal now too!)

I hope you can provide an explanation for your finding that makes more sense than mine.

Maybe they didn't die, but they look like tubes, it's possible that they starved slot but I know that they're immortal but I don't see them so much

I would keep the cold water tank going just let it do its own thing make a pop bottle auto. top off for your Salinity
