I think your best bet right now is to research dsbs and some of the problems with them that have come to light over the last several months. There really is nothing wrong with a DSB
, provided you know it's limitations and how to care for it, just like the animals in your tank the sandbed is a living breathing thing and requires some maintenance and, IMO
, has a finite life span. The exact length of time it will serve you will depend greatly on bioload, set-up and maintenance.
I personally have never used a DSB
in my main tank and have my first in a remote refugium, that can easily be removed from the system if necessary. Many will get the entire life of a particular tank out of a DSB
, since the trend is to keep upgrading to a larger tank before the lifespan of your dsb
has been reached.
