I have been saying this for a long time. Not only bacteria, but also other critters and pods etc. One species tends to become domminent and the numbers of the other species' numbers will get smaller.The constant seeding of different bacteria strains is also critical to it's success IMO.
Copper, I think in an established sand bed I don't think removing a handful will cause a problem. You would only disturb a small part of the top layer, which IMO gets disturbed by critters all the time. If you disturb too deep hoever, you could kill off the denitrifying bacteria. But if you keep it to a small part shouldn't be a problem either 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?
This sounds like a good idea. I think I will do that.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.
You are so right. I love fuges/DSB's and watch mine almost more than my display when I do have them. I love looking at pictures on the net of people's refugiums.Fuge’s are probably on of my favourite areas of marine tanks, they just so damm interesting and beneficial.
How do you run the lights in a DSB/refugium?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.
