CorydorasEthan Posted February 16, 2021 Share Posted February 16, 2021 Okay, so apparantly, my area is going to have power outage sometime during tonight or tomorrow. That means possibly no eletricity or heating for at least a 30 minute interval. How do I make sure that my fish survive? I have a 29 gallon and a 10 gallon (both communities with fish, shrimp, fry, and snails), and my sibling has a 5 gallon betta tank with snails. We have already covered the tanks with towels, but I'm not sure that will be enough to keep the fish warm. Also, I plan on aerating the aquariums by scooping out aquarium water and pouring it back in to give the fish oxygen through water movement regularly. Any suggestions on what else to do would be greatly appreciated. Thanks. 1 Link to comment Share on other sites More sharing options...

vvvinegar Posted February 16, 2021 Share Posted February 16, 2021 I've heard of pouring semi-warm tap water into plastic bags and letting them float in the tank to preserve heat- If there's time, you could also possibly change some of the water to reduce any toxins that might be potentially harmful to your fish. 1 Link to comment Share on other sites More sharing options...
Kat_Rigel Posted February 16, 2021 Share Posted February 16, 2021 For 30min I actually would not do anything. If your fish are in indoor aquariums, your house should provide enough insulation that a 30 or even 2hr lapse in electricity won't effect temp much. Keep in mind that water holds temperature differently than air too. The only thing I would do is, if you know what time the outage will occur, unplug your heaters and HOB filters. At the very least, confirm that they are on a surge protector so that they are protected if they are plugged in when the electricity comes back on. I would perhaps invest in a USB air pump or battery powered air pump in the future, but again, this is a very short amount of time and will make almost no difference to your fish. 1 1 Link to comment Share on other sites More sharing options...

I keep my house at around 20C (68f) and just so happened to datalog my 5.5gallon tank loosing heat (it was actually just a really bad heater that had too big a gap in its on and off temperatures). This is with a lid but no towel. You can see it lost about 0.75C (~1.5F) in an hour so 30 min is nothing to worry about and I'd do nothing. Incase you're curious i think the leveling off at hour 4 is when my furnace kicked in and it blows a bit on my tank. I'd only worry about fish getting too cold if you keep your house cold and you expect power going out for extended periods. Also not that larger tanks will cool slower as they have less area vs volume. Edit: To add to that I suspect many tropical species are fine at fairly cold temps for a day or two but I don't know that for sure, so again I'd love to hear from an expert there.

Trish Posted February 16, 2021 Share Posted February 16, 2021 Do water changes before power goes out if you know it's coming Calcium Chloride Heater (note must be pure 100% Calcium Chloride: 130F Plastic water bottle 500 ml bottle Add water to almost fill and 100 g calcium chloride Monitor temp take out or add more bottles Heat packs 113 F tape to side of tank with painters tape Tape near bottom, cover completely with painters tape Cover tank with Mylar Emergency foil blanket or reg blankets. Battery powered air pump Ammonia filtering *****Unplug regular filters or ammonia will be pumped in .**** Need filtration put air stone to bottom of aquarium place filter media over air stone or attach battery air pump directly to sponge filter. Don’t feed fish***** Power back on Let tank go back to normal temp Don’t feed fish right away Do a large water change Make an emergency kit Battery powered air pumps sponge filter airstone/ weighted airstone batteries D size for air pumps mylar blanket 52 x 84 -36 x40 for 20 gal heat rises thermometers flash lights 500 ml bottles heat packs/ 72 hr 110 F red line to outside for oxygen 1 to 20-30 gals monitor tape/ painters tape box filters air tubing blankets Tank will be ok at 63 degrees if necessary Watch for ICH 5 Link to comment Share on other sites More sharing options...
shkote Posted February 16, 2021 Share Posted February 16, 2021 I am in an area experiencing rolling blackouts as well and frigid temperatures in the negatives (-35° windchill) and the main thing I've done is insulate to keep the house warm, cover drafts around doors and windows, and cover tanks. With these temperatures, tanks can lose heat very quickly in a short amount of time. I was a bit surprised with how quickly the tanks lost heat in this cold... and even the house. I am a little worried about today's blackouts while I'm at work as they are completely random and I still have a few tanks with AquaClears 🤦🏻♀️ 2 Link to comment Share on other sites More sharing options...
Trish Posted February 16, 2021 Share Posted February 16, 2021 I survived a 7 day outage boiling water for bottles on our wood stove 24 hrs a day, switching out bottles to all the tanks. Battery air pumps are a must! I had only one casualty, the loss of my 13 yr old King Kong Parrot due to the fact I didn't have emergency air pumps at the time. The fluctuating water temperatures, even monitored the oxygen was removed and he most likely suffocated. A sad loss indeed. After 25 yrs with no generator I now have one wired in, although I have not used it yet. 3 Link to comment Share on other sites More sharing options...
Martin Posted February 16, 2021 Share Posted February 16, 2021 Hey @CorydorasEthan! I hope everything is going okay for your tank. Our power just came back on and I posted what I ended up doing in the other thread the others have already mentioned. I hope it helps you out. Everyone here is awesome. 2 Link to comment Share on other sites More sharing options...

There hasn't been a power outage yet, but I will be prepared if it comes! Edited February 16, 2021 by CorydorasEthan Link to comment Share on other sites More sharing options...
Celly Rasbora Posted February 16, 2021 Share Posted February 16, 2021 @Trish, super awesome information. I have a battery air pump on its way. I was lucky to not lose power … this time. I planned on getting mylar emergency blankets, but forgot them. I really hate buying from Amazon. Ugh. I love the calcium chloride heater idea. Science is amazing.

Kat_Rigel Posted February 16, 2021 Share Posted February 16, 2021 @Trishthe mylar blankets are a very good idea. I had to use one once (long story, but I got stranded) and it saved my tushie. I can imagine it would be very helpful with an aquarium. 1 Link to comment Share on other sites More sharing options...

I'll throw one in my glove compartment, you can never be too careful! Glad everything turned out well for you @Kat_Rigel 1 Link to comment Share on other sites More sharing options...
