What was your last big mistake?

First time I bought chalice frags I dipped them using water that I had just mixed up (obviously not well enough) and left them in for too long. When I got home 4 hours later there were a hand full of bare skeletons in my tank.
 
Leaving the ro/di running all night, on the second floor. I gave a 150 ghp unit. I lost an 8x8 section of ceiling, a 4 foot swath of wall and a 4x4 section of laminate flooring .
 
Thinking an egg crate cover on my QT would be enough to protect my new Watchman Goby from jumping out. Nope, he committed suicide while I was at work. I still have no idea how he managed to do that....
 
Hey guys, new to the hobby a few months ago. My big mistake happened when setting up my new tank and used some coral glue to attach 2 pieces of rock together. I placed the bottle of coral glue on top of my tank and applied pressure to the rocks. Without realizing it, my elbow knocked the bottle of glue over and it started leaking out. It was about 3 mins until I realized what I did and saw the mess I made to my acrylic tank. The glue leaked out and dried on top and was dripping down the front of the tank as well. After scrapping the glue off and seeing all the scratches on my new tank, I had to sand the tank down and polish it. I simple 30 minute project turned into a 3 hour job. That sucked!

I haven't been testing my RODI water for the last month totally spaced on doing that...I remembered yesterday to test it and come to find out its at 36pmm I nearly through my tds meter at the wall I was so upset with myself for being so careless aaaaaaargh
 
My latest, and most certainly won't be the last. After spending 10+ hours polishing my 6ft long 225G acrylic tank. Get the sand, scape and water in. Looked beautiful! Filled it with water and turned on the RW-15s. This resulted in a massive storm in tank. sand, cloudy. 3 days later..... All clear; but the acrylic was scratched up pretty bad in some spots. Painful lesson learned (RINSE everything prior to placing in tank with acrylic). :( Ce la vie. Will live with it for the time being.
 
I thought this might be a fun topic to bring up in order for people to share their experiences

Fun Topic? I'm not sure if I agree with you there but while I'm at it ill share mine. Adding 20 pound of live sand to a already established tank. Needless to say, sand dissolves into water pretty quickly, it also kills fish!:oops:
 
Thinking this new tank build was going to be cheap since I already have most of the equipment on hand. That was almost $1000 ago
 
My big mistake was used Amquel plus detox . They state that safe for corals. Lost all my sps corals and some soft corals.
My tank turned it to milk in a hour. I did 30-40 % wc asap. I could not save much corals.
Second mistake was over dozing 2 parts alk. due to Hanna checker reagent. Since that accident I use Salifert test kit.
I hope that someone learn from my mistakes.

Happy reefing
 
Last big mistake was having taken some seaweed (calerpa) from the sea for our temporary tank, and in doing so, introduced glass anemones to said tank, I then moved the corals into a brand new set-up, and although I took no calerpa, and no decor to the new tank, I managed to take a glass anemones on the foot of a leather coral, which is now obviously thriving and multiplying!
 
Buying a used freshwater tank and not asking the previous owner if he treated it with copper. One year later I decided to do a Triton test and realized why I couldn't grow any coral. Setting up a new tank as we speak and can't wait to see some positive results!
