Can someone tell me a few ways people have crashed their tanks? I'm trying to do everything possible to avoid it happening in my tank.
 
Alk swing when switching dosing products around the same time I forgot to turn heater back on after cleaning AIO frag tank for a night did a number on my chalices and encrusters. Acans didnt skip a beat though.
 
I’ve seen major wipe outs due to parasites most often; whether it be fish or coral parasites. A few accidents where the tank got contaminated with something toxic. I personally lost all my coral to a bad case of cyano that moved in super fast. My whole tank didn’t crash but I lost every single coral I had.
 
I also don't dose or use an ATO because I'm scared of malfunctions. Right now just doing weekly water changes
 
Once my carpet anemone died and while trying to remove him from the tank a cloudy puff of liquid came out of him and in a matter of hours every swimming things died.
 
How
Usually tank crashes (IMO) are from either:

1. Alk swings (especially SPS tanks)
2. Nutrient issues - People chase numbers and end up bottoming out PO4/NO3
Big of a dkh swing would it take to cause a crash?

Tank crash can happen because people don't dose and can't keep stable parameters

Tank crash can happen because people don't invest in ATO and can't keep salinity stable
 
nice thread heres my take

1. someone, anyone, show me a link where anyone on forums at any time added bottle bac to a new fish tank, some new fish, and they died so quickly we'd attribute it to cycling issues vs brook. unready tanks tend to go cloudy, other animals die, things happen that make proof beyond just brooklynella losses so someone post me a thread where bottle bac actually failed someone and the tank pics show it.

From the lack thereof or the posted threads, we'll know something about cycle crashes.

2. hardware fails and bad luck cause legit crashes, mother nature events. for pico reefers, nerfballs.

3. by following a popular setup and handling approach, don't clean your sandbed its destabilizing to do so, a massive majority will ride an ever sinking reef into the ground if one or more invasions alter the ideal balance- there's willing takedown I hate reefing crashes. I feel these are the most numerous, we practice invasion-prone peer training and lots of stuff is just wasted/tossed out and given up on. the top reason for crashes are I give up crashes in my opinion.
 
I’ve never personally had a tank crash. Early in my reefing career I was out of town for several months and the guy housesitting (living rent free) didn’t notice that none of the pumps/filtration came back on after a power outage and killed everything except two nassarius snails. I came home to a dead Sailfin tang, leopard wrasse, dragon wrasse, two clowns, lawnmower blenny, and bunch of corals inverts (and other stuff I’m sure I’m forgetting) all in a giant ball/mat of slime and algae. It smelled ungodly, and the dude didn’t even think to mention it when I checked in with him. It was awful. But that’s the only crash I’ve ever had.

This morning I saw a Fragbox video and one of their massive systems crashed recently, and I can’t even imagine a loss to that magnitude. I can’t help but think that as much stability and convenience that controllers and dosers can provide, they’re also a potential chink (feels really inappropriate to use that word) in the armor so to speak. Thinking or worrying too much about a potential crash is just too much anxiety and too paralyzing, I just do what has worked for me, do what I can to avoid it, and hope for the best.

ATO can also malfunction and flood your tank with RODI. I just add freshwater everyother day to bring salinity to 1.025/6

Damm I vacuum my sandbed every week... I know some people say not to others say yes hard to know what's the "right" thing to do in this hobby. So many contradicting opinions.

Lol I'm asking because I saw that fragbox video as well and it got me scared

I would take the ato and consistency over worrying about it adding too much rodi, especially now with redundancies built in

Don't change what you're doing, the tank has adjusted to your habits. It's when we get lazy our made environment gets upset.

Yeah from what I know also it's not about whether or not you vacuum.

It's that if you vacuum, keep vacuuming. if you've never then, don't. LOL. i hope that makes sense.
