Zalawala Posted January 26, 2015 Report Share Posted January 26, 2015 Hi there, hope I have this in the right section. The power down our street is getting cut off for 6 hours for maintenance, hopefully ends up being less than this. But I'm hoping someone can give me some ideas to keep the fish happy and safe. I have one 300L (adult and young Africans) and a 200l with baby Africans Any opinions are much appreciated Quote Link to comment Share on other sites More sharing options...
Godly3vil Posted January 26, 2015 Report Share Posted January 26, 2015 I personally wouldn't worry too much, if the tanks are pretty mature I doubt you will even notice anything different. Quote Link to comment Share on other sites More sharing options...
hovmoller Posted January 26, 2015 Report Share Posted January 26, 2015 What kind of filters are you using? Quote Link to comment Share on other sites More sharing options...
Zalawala Posted January 26, 2015 Author Report Share Posted January 26, 2015 HMF on both tanks plus cf1200 on big tank and origional trickle filter on the AQ850 Quote Link to comment Share on other sites More sharing options...
hovmoller Posted January 26, 2015 Report Share Posted January 26, 2015 You could change the water in your canister filter after a couple of hours by disconnecting the water in pipe and siphoning a bucket out through the filter. That way give the bacteria some fresh water so they don't all die in there. Quote Link to comment Share on other sites More sharing options...
Zalawala Posted January 26, 2015 Author Report Share Posted January 26, 2015 Thanks for that, what about the 850 filter? Could I try blocking off the drain hole to try keeping the filter material wet or what? Not that there is much water in that filter at anyone time anyway. Just worrying more about the babies now, my adults are hardy buggers, but in the fry tank I also have a few demasonis just under 2cm long and don't want to loose them Quote Link to comment Share on other sites More sharing options...
Adrienne Posted January 26, 2015 Report Share Posted January 26, 2015 When the power goes off the canister won't pump dry - the water that is in there will remain so. I wouldn't be worried about the media and bacteria in the canister, it will still be viable after six hours. My suggestion, if you are home, is to stir the tank water around a couple of times every hour for about 5 mins. It will allow for gas exchange. Your other alternative is to purchase a battery powered air pump - specialist shops stock them. Quote Link to comment Share on other sites More sharing options...
Ira Posted January 26, 2015 Report Share Posted January 26, 2015 I'd just use it as an excuse to give the filter a quick clean afterwards. I've had a tank wiped out by, presumably, the water in the filter going bad after a couple hour power outage. So I usually switch off the filter after the power has been out an hour, then give it a quick clean afterwards. Mostly just to make sure it doesn't dump any crap back into the tank when the power comes back on. But, I've also gone 18+ hours without doing anything with no issues.

David R Posted January 28, 2015 Report Share Posted January 28, 2015 IMO knowing that it is coming, I'd clean out the canisters a day or two before hand to remove as much physical waste as possible. Changing some of the water in the canister as Hovmoller suggested is a good idea too, the last thing you want to happen is for the canister to turn in to an anaerobic environment and spew a heap of nasty water back into the tank.

Zalawala Posted February 4, 2015 Author Report Share Posted February 4, 2015 Well we had the power cut today...I thought it was Friday and I was away so I panicked a bit when my neighbour rang to let me know it was off. Fortunately it was only off for about an hour this morning and then when I came home this arvo it went off again but flickered and I think my cansiter is caput. Grr. Thanks for all the advice everyone, good handy tips for the future Quote Link to comment Share on other sites More sharing options...
Adrienne Posted February 4, 2015 Report Share Posted February 4, 2015 Cannister might just have an airlock in it. Quote Link to comment Share on other sites More sharing options...
