I like the look of the sand bed better. Many people will argue from both sides, one being that the dsb
will eventually crash or that the BB is only a fad. Either way, I find it more of a preference issue.
Do you like the look of sand better or the BB?
Would you rather siphon, or buy criters and still vaccum?
What proof is there to either side? (Not disputing any, just provoking thought)
Now what kind of substrate are you running now? By your pics it almost looks like crushed coral.
Also are you having any tank problems that would get you to thinking about a change?
