The constant seeding of different bacteria strains is also critical to it's success IMO.
ok i'll buy that, so how do we do this? Just take sand from each other's dsb's? Won't even a little sand removal disturb the whole thing?
Following the GARF philosophy it's also a good idea to take some liverock and break it up into small bits and sprinkle it over your bed. This also harbours beneficial bacteria and fauna and can be swapped amongst hobbyists.
Fuge’s are probably on of my favourite areas of marine tanks, they just so damm interesting and beneficial.
Actually a dsb all on it’s own in the sump area is also a refugium. DSB/Chaeto fuge is probably the right name for it.
There are so many ways/variations/styles to do refugiums. Fuge’s are probably on of my favourite areas of marine tanks, they just so damm interesting and beneficial.
