"crashes" can occur anytime the ph is disturbed by a large spike of ammonia, or after a water change with impure water...(this was on a thread a week or two ago, where the tank had just been through a water change) The water particulates die off, and almost begin to "snow" from the top of the tank down...the ammonia spike then is catastrophic, usually ending in a terminal tank that has to be stripped down, and restarted from scratch.
This is why we are so vehement about aging the water prior to a water change in the octo tank...you can just use a 7 dollar rubbermaid 50 gallon garbage can...keep it stocked with salt water, and use it for all of your changes...most of the chemicals/toxins in water will boil off within 24 hours.
glad to hear this wasn't the case in this situation.
Cthulhu77, other than powerheads (in congunction with live rock), what type of filtration do you recommend for a rubbermaid garbage tub/feedertank/water change source? I have been planning on keeping one for a while, but would appreciate your input.
By the way, I will formally introduce myself soon. I have been lurking for a while, and am nearly done purchasing all my equipment for my first Octopus tank. I am seriously overfiltering, but this can't be wrong... right?
I am a veterinarian in Michigan that specializes in small and exotic pets, but this will be my first ceph pet.
Thanks a lot, and thanks to all of TONMO!!! This is an excellant source of information, and has helped me tremendously.

Welcome to Tonmo!
I use the garbage can for live rock and water for changes...with a Magnum filter (carbon only)...the 330 makes the water move around just fine...I am sure an eheim would be alright too, I just like the magnum's ease of use...
Yep, you can't go wrong with overfiltering! a clean ceph is a happy ceph, after all !!!
