    Does anyone know how long the filter pumps can be not functioning (because of a power failure possibly) before the bacteria start to die off

    By the sounds of it, there must have been a big power failure in JHB today. I was at Idol Marine (Midrand) this afternoon and there power was off for about 4 hours

    How long is a piece of string ???

    This depends on many factors, most importantly the bio-load of the tank (number of fish, corals and other inverts using up oxygen vs. the volume of water in the tank...), but also on the depth of the sand bed, the permeability (particle grading) of the sand and (density) of the rock.

    If the DLSB contains a large number of worms and other critters who burrow through the sand, and in so doing displace small amounts of water, this slight water movement can increase the length of time before the sand becomes anoxic. Having a few fish in the tank (compared to having no fish at all) could also extend the time, as their swimming will displace water, and ensure that "fresh" oxygenated water is circulated around the corals, live rock and sand bed.

    As with most things in this hobby, a "balanced" system is the best and safest option.
