Well, I am sure I am not the only one. If you look through my threads, you'll find the baby shampoo incident

I had an incident many years ago when my daughter (15 now) was only about 4 or 5.. I was cleaning the canopy and stand of my 120 gallon salt tank, and I was using Murphey's wood/oil soap (the canopy and stand were oak) and the phone rang.. I ran and answered it and the moment my back was turned, my daughter poured the soapy water straight into my sump.. I watched in horror as immediately the oil soap was pumped into the tank.. The water immediately turned white.. It was freaky and awful!! I did a massive water change immediately, and let the sump do the rest (I was glad to have bio-balls back then to rinse off instead of live rock in the sump!) the sump was so powerful, that unbelievably I lost NOTHING! Unbelievable huh?
I wish I could say the same about my other crash.. I may add that one another day.. Don't want to talk about it right now lol

Your post reminded me of my soap incident

Toddlers and preschoolers can be such monkeys! It's a good thing that they're so darn adorable (most of the time). My three-year-old is well behaved around our system, for the most part.

So was mine! She was always soo good! That's why it blew me away when she did that.. And she seemed so surprised that I was upset, she started crying! So I had to comfort her while trying to get the soap out of the tank! Lol! You called it, such monkey's!

Well the poll don't seem to show up in tapatalk. Anyway my 33 crashed when I was away for a long weekend & the heater broke causing the gfi to trip. Water temp was 65F when I got home. Lost all the fish, all the SPS and nearly everything else. One brain coral made it (still have) some hermits & snails and a RBTA that I still have today

Yes, I'm using tap a talk as well...
So my worst crash ever was in my 55g, I had worked a long day at work, and I came home just beat! The sump I was using on the 55 was major overkill, as I had bought it a few years prior to go in the 120g I had at the time..
Anyway, I unplugged the return pump to feed my corals, and my heater is in my sump. I was just so dam exhausted that instead of plugging it back in half an hour later, I forgot I unplugged it at all and went to bed!! Tank is on lino covered concrete, it was winter.. My temp dropped dramatically and I lost every fish I had. No corals. I was absolutely devastated... The money you loose is totally secondary to knowing such a stupid slip took the lives of those beautiful creatures.. I felt like such a horrible murderer for a long time. It was hard lesson, and a mistake that I will NEVER make again! And yes, I did it, I said NEVER!! Lol

Voted for multiple, because it was multiple.

Power outage for 12 hours in January, caused die off. Excess nutrients cause macro algae to grow like crazy, fill refugium andcaulerpa to go sexual. This caused another cycle, too long for SPS, so there was SPS die off. Calcium reactor was still outputting the same (I did sometihng stupid), and my levels went nuts. API Test kit still showed 7KH, i thought i was good. Got water tested at LFS, 14DKH, bought another test kit(salifert), and showed 14 as well. (Other) Ouch, lots of water changes, small issues with salt being high KH (12KH in new water), but didn't cause too much issue, got more salt and rolled the bucket better this time :P. So things are finally looking up and i wake up to find thatmy kids put a graphing calculator in the sump, complete with batteries the day before. (my fault too, i left the fish room door unlocked with a 3 year old and a 2 year old) Big reset button again for the tank. Overall, lots lots, learned lots, and now things are going GREAT. My tanks still got some aiptasia issues, but coral that had completely browned out(bleached then brown, totally dead) is coming back. I went through and purged the dead-dead stuff, the recovering stuff is looking good.
