Hawk82 thank you for posting clear documentation


when the tank cracked you had to act fast, you separated the major components quickly and effectively

Reef Tank CPR
this thread will be to track emergency reef saving procedures, with quick reactions.

look at this job underway.

we are moving away from tank crashing diagnosis and well into fish disease diagnosis, using clues shown in his opening tank pictures.


Notice our first move in most jobs: the first thing you do when you suspect a crash impending for your $$ coral is you drop the overall light levels you were used to running during peak production

that's a big, big sunburn risk. you instantly create lower light/cloudy light reef low burn with high blues and no white spectrum if you are arresting a coral bleaching event.

we will then ensure each reef is cleaned out of invasions, breathing and expressing waste cleanly inside vs pent up with algae and other plugging matting invasions, then a big water change, then we focus on sustained feeding and water changes exactly like an exercise program, for the reef.

we don't let reefs sit idly by here, this is an actionable thread and we focus on the physical ways available for saving and preventing reef tank crashes where possible. we can document crash recovery for the extreme examples of loss, we can use any crashed system as a new biofilter as well in a rebuilt tank

the filter bacteria did not die during a crash, the higher animals did.



Fish disease is going to be a big cause of crashes here, but folks will think a tank parameter they can measure caused the initial fish loss or crash

skipping disease preps in mixed fish system crashes your tank because they all wait to die until you're on vacation, overloading your filtration setup.


it is rare rare that your crashing system happened from a parameter you had to pay ICP to detect.


stray voltage issues account for a vastly small % of jobs

storms and electrical outage events are a decent contributor to crash study threads, but above all, top cause of tank crashes in my opinion is fish disease wipeouts.

light power adaptation as a control in reef tank CPR runs




the reason for collecting light-controlled STN / RTN prevention here is because we did it without CIPRO use and we have been using this method for several years in the sand rinse thread to prevent crashes when moving tanks, being able to control light intensity (before the tank insult where possible) is a big deal helper in stopping coral losses during and after tank crashes or stress events

not relying on meds to control sps and lps health helps reefing, everyone can control their light levels

if you can't adjust your individual LED's then use creative black tape strips to physically block light off your tank lid, or the shielding from the light if it's an LED system/most are nowadays.

we did not focus on measuring things and guessing at the param levels, we did light ramping. once we get 20-30 of these on file, we'll have a pattern to vet.

rip cleans and lighting control is something any reefer can do to bring back a crashed reef tank. the filter bacteria will be the last to go, able to endure nearly all insults some live rock will ever see. we clean out all around those fixed bacteria, adjust lighting, hold for two months with good feed and most reef tanks can be brought back. corals can be intercepted from loss etc
