I think they'll be fine. Tank temperatures generally fluctuate a little.
Thanks Reginald. That heater almost made a stew out of my goldies. It got stuck and kept heating the water. Lucky me, I did catch it just on time.I think they'll be fine. Tank temperatures generally fluctuate a little.
You right. Thanks.A lot of people have issues with their lighting heating the water several degrees during each photoperiod. Not a big deal.
Thanks. I am cranking up my house thermostat to 76F at night until I get the new heater.My heater evidently came from the factory stillborn (curse you, Aqua One) but I didn't find out until several weeks later when I added a new thermometer. The temperature swung by around seven to eight degrees in a day. Didn't lose a single fish... they're tougher than I thought (angels, tetras, corys, barbs).
A few degrees doesn't matter. That's what mine get every water change.
Thanks kozlany but, I do have lots of plants in that tank. Anyway I did crank up my house thermostat to 76F at night. Usually I have it at 76 during the day and 72 during the nigh.Goldfish survive outside in the winter in the northern US and Canada with no heat as long as the bottom doesn't freeze solid. If it's just goldfish in the tank I wouldn't even bother with a heater. I had ice over 2 feet thick in my pond and goldfish that were a foot long. Cold doesn't bother them.
Thanks Diana.Wrap the tank in a thick towel during the coolest time (night, I assume) to stabilize the temperature.
