For every article that I can find that speaks positive about DSB I can find several more that say negatron ghost rider.
Long term DSB is a risk.Many will say will not work period,I dissagree, I think taking care of them is vital to success with them.
You can only simulate what the ocean does, not replace it. And DSB is one of those simulations that cant truly be mimicked. There is a lot more going on in the ocean with currents,critters and below the sand table that we can never copy.
Among other things high flow is needed to keep them safe, and critters keeping it clean as well. Just because someone can write an article and that doesn't mean its right. I just had a published reef book tell me in writing last night that you don't want to exceed 74 degrees in your tank, and have one crab per gallon.
Ive never ran a DSB(I watched it backfire personally, and have heard too many horror stories) so I know better.
But I do know one thing, there is a reason you see less and less of them as time goes on. They were a fad, and the long term effects weren't known for many many years. Now that time has proven them a poor choice, people steer away from them.
Now the topic was remote sand beds...some will say they are worse, others say better. Flow being one of the keys, I personally say they are a safer method, because you control the turnover in a small volume of space better than the large volume of a tank, plus detritus usually happens in the DT, not the sump.
Look bottom line, it should be a really simple concept to understand: if you fill something with bad stuff and it cant consume it fast enough...its going to get thicker and thicker, until it can store no more.
When that happens yes...it "Blows-UP" or releases, belches,farts,vomit's, expelled, gives up...pick a word. The concept is all the same. DSB can go years w/out problems, but you run a risk of a breakdown, much like a car with high miles. The longer you run one, the bigger the risk.
For those with DSB, I'm not saying to panic and think the sky is falling. Just take care of your DSB, and you should be fine. You do have to understand how to properly maintain it. You cant just sit ho-hum thinking everything is hunky dory, that I absolutely promise, will bring down the thunder, maybe not for a while...but it will happen end of story. Do the proper maintenance, and have the proper critters. Just be aware of the monster looming in the dark.
They mostly come at night...mostly.
that was really well put...
