Why do tanks crash?

[amoreira]

My tank crashed due to the recirculation pump (from the sump to the DT) failing overnight. The oxygen levels in the DT fell and all the fish died. I think most crashes happen as a result of equipment failure. Cheap equipment is more prone to failure. For instance, many opt for cheaper pumps, which fail as they have a big demand on them (running 24x7 for years at a time). Cheap heaters will get stuck on and cause overheating. Skimmers overflowing will empty out the sump, etc.. IMO, get the best equipment you can afford. After all, it is a life support system for your precious reeflife. Losing them can be a big shock too (always use a GFCI).

I think the ideal thing to do is run a pair of smaller pumps. Or (if your system is small enough) run an eheim. i'd bet my life on one =)

I agree, i lost all my coral and inverts when starting out due to a cheap heater sticking on. My advice to anyone starting out on a budget is that good used stuff is better than shiny new crap.
