Black goo is good for growth on corals. I just stirred up all the goo in my sump and my corals loved it they fed and just opened right up with lots of polyp extension.
Just my 2 cents everyone has their own way though.

Thanks again everyone! :)

lol...
what do you guys figure happens to all that "black goo" when you don't have a sand bed to trap it?
I suppose it just ceases to exist?
lol...

It's removed by siphoning, filter socks and your skimmer. If you just leave crud to rot in your tank like in a DSB nasty things happen. Better to keep your tank clean IMO. I keep 1/2" to 3/4" of sand in my tank and stir it regularly so nothing builds up. Tried the DSB thing but it didn't work for me. Much lower nitrates, and a cleaner tank after it was gone. Removing a DSB is one of the most disgusting things you'll ever do!

I think that unless you do it properly, dsb's have no merit.

Why is it that so many like James Tullock in my living microcosm book speak so highly of dsbs?

He does say that you need to install it properly and have enough "critters" to maintain it for you but even with changing it every few years, sounds a lot easier than all that maintenance you are doing.

Man, thats a lot of unnecessary work IMO.

My first tank was a 12 gallon aquapod, no skimmer, MASSIVE bioload and a DSB.
That tank was a brick, I credit the ability of that thing to keep everything I ever put into it alive to the dsb that it had.
I had 2 clowns, clown goby, gramma, red reef star, peppermint shrimps and a boxfish not to mention a tonne of coral (all came with it when I bought it and I didn't know better then).
The dsb in that thing was probably 5 years old and it provided food, calcium and trace elements and biological filtration for the overcrowded tank perfectly.
I would NEVER set up a nano tank without one now period.

I have tried both. I liked the look of my last sand bed but the grain size was too small and a pain, blew all over the place. The next tank will have a sand bed but it will be a larger grain size so it stays put.

So are you saying my nano will fail because I,m bare. :smile: What exactly does the sandbed provide my nano for stability that my bare
bottom does not?

And FWIW, I have used sand beds and bare in previous tanks, including a couple inches in my just down 90g and my 170 that was once featured back in 01 on RC.
Thanks

Congrats on being featured on RC 8 years ago...lol
I stated that my exceptionally overstocked, low tech nano functioned seamlessly with a dsb, where do you see anyone saying that a "nano" (and you are being very general here, I was being very specific) won't work without a dsb?

where?

and i specified a couple fo times in this thread where a dsb is handy, reread the whole thread please as you must have missed it when you read it before your last comment.

Just to comment on DSBs, they're not the big bad scary things they're lately being made as. Had a 4-6" for about 3 years, no special efforts and when I took it down, no sludge or funk.

What ever method you use.......do research and do it right!
