my current set-up has bean cycling for 5 weeks now, I still have that dark green algae bloom.
but I have started the base of my 1st SW tank with too diffident grades of CC (Fine & Coarse)
but from other post that I have bean reading it sounds that the better base for a SW tank is marine safe sand that can become "Live sand"
1) can my CC not become live CC?
2) is there any negatives from having CC and if so what are they?
3) if I do chows to go with sand should I
A) add it on top of the CC
B) remove the CC and then add sand
