Those of you with refugiums, which do you have as a substrate, sand or mud? I had sand, then switched to mud but was thinking of going back to sand. Which do you think is more beneficial?
I tend to view the mud as a advertising ploy. I know mangrove swamps etc contain mud and lots of diverse things, but this is a closed system, and virtually everyhting we keep comes from the oceans and seas away from mud, and does very well in sand substrate. Nothing wrong with sand IMHO....and its more natural substrate for what we keep.
if you are using chato having a mud sump is pointless, you would only need mud if you have mangroves or culpra and with mud you will cut back on your pod count
in my opinion go with sand
