Hi George,

First, I missed giving you a big WELCOME to CANREEF.

If you have a chance, there are many thread on the sps forum at Reef Central on bare bottomed tank. Some here also, plus others if your interested.

Although many like Bev, are now incoprorating it into their tanks of all kinds, it started out as a way to keep high flow sps tanks clean. To many nutrients gathered with dsb,s. They also run larger than normal skimmers and usually run them wetter than normal to remove the organics and detritus than is kept in suspended in the water by the higher flow.

And as you likely know, its nothing new. We kept reefs that way back 15 yrs. ago but not with the skimming strength we have now. I have also read many articles regarding German aquarists that have always used and still do, this method, which is part of the argument used in the bb versus dsb threads. I,m surprised that you mentioned dsb,s are the thing there now.
