Kien,
These questions were answered. "How long was the power out? 4hrs? Slightly more What is you total system volume? 1100 litres How many fish? Too many apparently How did the inverts fair and which ones do you have if any? Fine until ammonia spike" BTW, in case anybody bothered to check (which I did before I posted), the OP was NOT on Canreef since the 15th, when the original post was made, until she responded to yesterday, which explains why the questions were left unanswered. Again, everyone here should remember Canreef is not the OP's home site (UK-based, not a Canadian reefer). From my own experience, I once made a totally stupid & very costly (for my livestock) mistake of forgetting to turn my power bar back on one of my tanks after a water change. I was in a rush because my father-in-law had called while I was in the middle of doing water changes with free tickets to a Canucks game. I rushed through my water change, plugged everything back in, but took off without looking to see if the power came back on (which it didn't since I turned off the powerbar before starting the water change). By the time I came home, I had lost 3 fish , which I felt very guilty about since this was a totally preventable accident. The tank was much smaller than the OPs, but my bioload was also much smaller, yet in the 4 hours I was gone to watch the hockey game, the oxygen level had dropped enough to kill the biggest fish, which then increased the rate of oxygen depletion and caused an ammonia spike. So yeah, a tank crash can happen in less than 4 hours if all the stars align against you and your tank (Murphy's Law). Not one of my finer moments in my fish-keeping career, but I now am very anal about ensuring everything is plugged in and working after a water change. This is another lesson I hope others can learn without going through it themselves. "Double check everything post-water change"!!! Anthony

Canucks probably lost too! Insult to injury!

If I'm honest I don't actually know wha the plan is, I think I'm just leaving things to settle for now. Literally can't afford to restock at the mo net so I don't really have an option. I'm selling off some coral because I'm more of a fish person

I actually have a learning difficulty which is why I speak slightly slowly, one of the reasons I started doing the channel was for that (I'm improving compared to my first videos you'll notice) |

No one pointed it out to me, I normally post and then come back to check, I make my videos in an effort to help beginners. Not experts, I've been doing this nine years now so I know a little but I never claim to be an expert.
I've given my explanation in the video, everything which I know pointed to tank losing oxygen. I had a reasonably heavily stocked tank and I think that probably contributed to it. The only thing I did the night before was clean the glass. Quote:

No, actually this was a few years ago and the Canucks WON!!! I've only been to a handful of games, but they've actually won every game I've attended over the last decade or so. This wasn't true in the 80s or 90s though.
Rich, it was only a 34g RSM, so much smaller than the OP's reef tank. I never had much luck with that tank and tore it down and replaced it with my 93g cube after this incident. I lost a med. Marine betta, a Naoko fairy wrasse and a third fish I cannot remember now. It was a complete Brain-fart moment and I still feel bad that my carelessness lead to their needless deaths. I admit I was really shocked that they died in such a short period of time without circulation. Before this happened, I would have sworn a tank could go half a day without power without suffering any casualties (unless overstocked like my main reef tanks usually are). The third fish may have been a mandarin goby. My leopard and yellow canary wrasses survived, but they hid in the sand for another day or so. I was in the process of planning a switch over to a bigger tank and had just recently added the MB in anticipation of that upgrade. My theory is the water change dropped the tank's ORP and without turning on my powerbar, the oxygen level dropped quickly. The 2 wrasses survived probably because they are used to surviving on lower oxygen levels when they bury themselves in the sand every night. As long as the pumps were working, this bioload was fine but without circulation it was clearly too much for the available dissolved oxygen levels in that size tank (4 small fish & 1 med.). I had done a 10g water change and did another 10g change when I came home from the game. Now I own 3 battery operated air pumps, a generator and a battery back up (UPS) in case of blackouts to ensure that I can at least keep my tanks oxygenated. I also check every piece of equipment after each water change to make sure everything is plugged in and working again. |
