I did a Dsb
in my cube and my 72, I based it off a lot of research. I decided for my 194g that I won't be doing a Dsb
in display or the sump. I will fill the sump with rock. The Dsb
looks messy to me, it helps reduce nitrates, but only if not disturbed, most people like gobies, etc that disrupt the sandbed. There are other ways to reduce nitrates that won't cause potential catastrophic results.
Why I changed my idea on DSB
1. I had a powerhead fall and create a horrible mess in the sand, if the tank had been any older it would have crashed. Accidents happen.
2. I want to run my tank as long as possible, we are talking 20-30 years, and there are no tanks this old that ran a Dsb
, actually some of those people said they could get about 5-7 years and then things would start going downhill.
3. I want a large goby and they tend to eat the creatures in the sand that provide the mechanism for converting nitrates to nitrogen gas.
I have to say, both tanks once set up had zero nitrates after about two months, with over feeding and irregular water changes.
