Sump media...

[Metrontech]

Hey guys, hoping to get some help on setting up my new 55 gallon sump

I have a 55 gallon reef tank running for around 3 months now

I a bunch of LPS and some softies in there, and they seem to be staying alive...the fish too...

I have decided to up-size my sump to a 55, mainly because I bought it for $60 already made

I added a divider just before the return area for media, that seems to be what alot of people have done

Wondering what media I should put in there. I know carbon is key, but heard that it affects the coral etc.

Any suggestions, along with maintenance procedures would be great...

Thanks again

Mike
