I am trying to understand why I would have black/gray sand on the surface of my DSB. I thought that would develop under the top layer if detritus was caught in the sand? If I notice dark sand but no gas bubbles being released, and no smell, what's the prognosis for the tank becoming toxic?
Hi folks! Long term lurker here, first time poster. I recently set up a small 30 gallon reef tank with a 3" fine-particle sand bed. I cycled 50 pounds of live rock in it, then added 3 small fish and some reef janitors. For sand sifters I tossed in 15 nassarius snails. The live rock I placed...
I'm starting to get air bubbles rising from the sand. i have raked through the sand to get them to rise but a couple hours later they are there again.
what are they from?
are they bad?
How do i get rid of them?
I called it an HRDSB to distinguish it from an RDSB. HRDSB is a Hikk Remote Deep Sand Bed. What I am referring to is a 5G bucket setup such as this one:

For purposes of this discussion the following terms are used to describe certain things:
Live Rock: This seems to be self-explanatory but it will include any DIY rocks, any type of actual rock that is used in a tank for a surface for the bacteria to live on.

I just realized after reading around on here... I have a dsb lol The lady at the lfs said 1 lb of sand per gallon... so i have 15 lbs of sand in my 14 gallon...
My LFS ,for as long as i can remember, stirs the sand bed in their 3 display tanks daily.

I just spent three hours reading through the DSB myth thread and decided in all fairness to put up a pro DSB thread. Although I have not been in the hobby as long as many on here have. I research constantly for ways to improve the quality of life for the animals I choose to own. This is in no...
Looking at replacing my Combination Remote DSB and Refugium with a new design. I am looking at 2 17 gallon acrylic tanks which when I get it replaced should be about the same amount of water as my current system, but it should maintain its level a lot better.
First things first though, I am...

I'm looking for suggestions of brand/type/grain size to replace the top layer of my arganite bed. I have issues with detritus buildup and cyano/nasty growth in the deeper visible layers at the tanks edge. Is .5-1mm standard? I'd love the oolitic stuff, but figure that it'l make major sandstorm...
It seems that one of my good friends has decided to get an early birthday present for me. A 90g tank setup. Now as I have not seen it yet, I'm not all together sure what's coming with it, but I now have to decide if I want this in addition to the 55g or in place of it. I know I'm missing...

The display is a 125 gal AGA with dual vertical overflows.
I will have one overflow drain directly into the skimmer side of the sump. I will have the other overflow drain into the fuge side...tee'ed off right above the fuge as...
