Green slime

[Tlro]

Anyone know what this is? Is it harmful? It's a dark green slime. It almost disappears at night when the lights are off but comes back when they turn on.

That would be Cyano.

Ahh. So don't worry about it then?

Yes worry about it. Not good. Start siphoning it out with water changes and cut back on your feeding. Also- of it's in a dead spot you may want to look into adjusting flow after your next water change

I always thought cyano was a rust color? Guess I'll have to step up my water change regime. I usually do 25% every two weeks. Should I do 10% a week instead?

The most common color is red, but there are others like green and black.

I'd say about 2 inches of sand and crushes coral mixed. I know crushed coral sucks. I put it in before I knew any better and now I'm too lazy/scared to change it.

How old?

 

[Tlro]

The sand is about 8 months and the CC is about 3 months

How would I go about changing my substrate without totally tearing everything down?

Well start takin hand fulls out ad just put it in your sump or in a filter bag I woulny worry about it all cause if your going to add sand it will help for little pods and things to build little tunnels and what not I would just try and get the main volume of it out but try not to totally remove it b/c that is biological filtration and it may cycle your tank if you remove to much at and throw it out
