Orange Coraline?

I did a pretty large water change today, and just recently noticed bright orange coraline on my overflow. There's actually three colors overlapping in places. Pretty cool though I understand it likely won't stick around?

 

Awesome, my rocks are covered in lime green at the moment, 80% in fact

 

Apparently there's a blue out there also. I think it'd be cool to have a bunch of different colors.

 

I do have some orange, red and purple/pink but for some reason mostly lime green, blue would be very nice, but yes i too understand it will change to the more desirable purple colour eventually, i had grey/white to , but that was dead when i added it lol

 

Mine is all white with a faint purple color.

 

This happens to me when I have a significant change in ALK. The orange is usually just dead coralline that turn grey or white eventually.

 

I have some blue coralline, its pretty sweet!



My coralline also turns that cool orange when it dies. I took out my mp10 pump to clean. i dropped it in a bucket of vinegar and water for a few minutes. afterwards my pump was orange for about 2 days before turning white.

 

Hmm... I did just do a big water change to try to correct my values. Perhaps I should remeasure them. I also made up some kalkwasser! Not to dose yet

 

Buy this one of a kind Rainbow Mp10 for only $1,300 today lol.

 

When exposed to air and the high light you usually have dieoff
