Just noticed today that my heater in the 75gal died. Found a replacement, But the temp is down to 70deg. Any Ideas on the rate i should get it back up, like a deg a day. Have no Idea how long its been down.
Thanks Lee
I think as long as you are just using a tank heater to bring it up to temperature you can’t raise it to fast. You would probably be OK to add a second heater to bring it up a little faster (besides, never hurts to have a backup in case 1 dies)
I would think faster than a degree a day, but I don’t have any hard numbers for you sorry.
i agree with deangelo. im not sure a heater for a 75 watt tank can really pull the tank up too fast. 10 degrees in a 24 hr period is probably what u will end up with, shouldn’t hurt a thing. not in my experience anyhow… (375 watts is what u need, so a 350 or 400 watt heater would be perfect.)
Thanks guys, What Iv got in there is a 300 watt heater. So basicaly just set it to the desired temp and let it do its thing. I was just worried it would raise to fast. Thanks again Lee
It shouldnt heat it up to fast, with that wattage you should be fine. I have 2x300W heaters in our 90 (one as main, one as backup set at 74) and it takes quite a while to warm the tank up significantly.
in winter, i set my heaters for about 77. during the day the lights run the tank up to 80, and cool to 77 at night, whence the heaters come on for a little while before the lights com on again. in summer i take the heaters out of the tanks all together. dont need them then. temp ranges seem to work for me. on the reef, water temps can and do swing every day. the tide can bring upwelling from the deep up the reef wall and drop temps to 74. the carribean shallow reefs run about 73-76 in winter, early spring, march april. I know from snorkling. its cool water. so natural reef temps do vary thru the seasons, and day and night, and also affected by storm currents. but corals and fish do grow faster in warmer water temps. higher metabolism.
As far as how quickly I have brought it up the same way you Lee did in the past several times. When I first moved into the apartment I had some surge strips with only lights plugged into them which I would turn off at night time. Had a heater plugged into a surge strip I turned off one night, but everything in the tank lived through the mishap.

Ken we talked about this before. I think there is a huge difference between a 2 second event that occurs once every 2-3 days and having you’re tanks reach this tank for a solid 6 hours every day. Fish can also jump in and out of areas if they don’t feel well when they are in the wild, in you’re tank they are stuck in the glass walls you put them in. Don’t want to get too much into as this was discussed in length in another thread, but I don’t think a short random event in the wild justifies extended daily lows in our tanks.
