Wade Posted August 6, 2013 Share Posted August 6, 2013 My tank has been running a lot cooler since I made the switch to LEDs. Following a 20% water change yesterday it's been running at about 76.7 degrees which is about 2 degrees colder than usual. I heat my replacement water to 78% so that shouldn't have cooled it down that much. Is 76.7 too cold? it'll probably drop a degree or so through the night I imagine.

haze152 Posted August 6, 2013 Share Posted August 6, 2013 I never let my tank drop below 78 just my 2 cents in sure others will chime in Quote Link to comment Share on other sites More sharing options...
victoly Posted August 6, 2013 Share Posted August 6, 2013 its at the bottom limits of what I would run regularly, if i lived in a place that wasnt 1,000 degrees all the time. I'd have a heater that kicks on at 76 and heats to 77 Quote Link to comment Share on other sites More sharing options...
Bogdan Posted August 6, 2013 Share Posted August 6, 2013 Randy Holmes suggest 76-83. Quote Link to comment Share on other sites More sharing options...
Juiceman Posted August 6, 2013 Share Posted August 6, 2013 I think you're fine if it never goes under 75. Better to run cool than run HOT. 1 Quote Link to comment Share on other sites More sharing options...
bige Posted August 6, 2013 Share Posted August 6, 2013 Do you use a heater? I don't think 76 is too low but I wouldn't want the temp fluctuating all over the place. I try to keep mine at 78. And I don't have a heater. I use fans to control temp. Sometimes I put fan right on top of water then move it if temp drops. I would shoot for 78.

+o0zarkawater Posted August 6, 2013 Share Posted August 6, 2013 Being the odd man out..... In order to keep my tank below 80 during the day with the lights on I keep my AC at 70. Also I love the cold. Most days my tank goes from 72-74 in the morning to 80 in the evenings in the summer. Every day. Winter time my tank has been as low as 65 with no ill effects. YMMV 1 Quote Link to comment Share on other sites More sharing options...

I use todo this too but got sceered because of the inconstant numbers. Aqua tek says they never use heaters and don't even check temp because Texas doesn't get cold enough or stay cold enough to cause concern. Looks like your good wade. My ac went out yesterday and it was 90 in my house. Tank stayed at 83. My wife said "I've never been to a fish store that wasn't this hot". Meaning Aquadome. And they seem fine.

bigmike015 Posted August 6, 2013 Share Posted August 6, 2013 In the mornings my tank is about 77 and in the afternoon its around 79, never over 80. Thats with a 10 in fan on the sump and 3 4 in fans under the canopy. Also running LEDs. Quote Link to comment Share on other sites More sharing options...
Wade Posted August 6, 2013 Author Share Posted August 6, 2013 Nope, no heater. My MH lights always made it run hot so I needed a chiller. Looking at the graphs on my Apex it looks like it's not got below 76.4 so I guess I'm ok. I'll keep a close eye on it over the next few days. Thanks all for your input.

esacjack Posted August 6, 2013 Share Posted August 6, 2013 no heater here either. In the winter the garage tanks have a few 100w cheapy heaters I have set on the RKE systems as an on/off cycle. Quote Link to comment Share on other sites More sharing options...
Sascha D. Posted August 6, 2013 Share Posted August 6, 2013 I have a 400w heater set to 78 degrees but I've never seen it turn on. My tank stays around 84 during the day and 80 at night. I don't like the AC so my house is never below 78. Quote Link to comment Share on other sites More sharing options...
Timfish Posted August 6, 2013 Share Posted August 6, 2013 I've had pink pirdsnest bleach out at 72 degrees but the other acros and Poccillapora were fine. I've also had Teal BTAs bleach out in the mid 60's while Brown BTAs were fine. I prefer to keep my tanks between 78 and 80. Quote Link to comment Share on other sites More sharing options...

YMMV wow you have a good a/c system. if i set mine at 76 it runs all day long in the summer. so, mine's at 78 in the day and i have three fans in my office to keep my at or below 80.

Sascha D. Posted August 6, 2013 Share Posted August 6, 2013 My house stays at 70 during the days, 68 at night I would be wearing three layers and rabbit fur boots in that climate! 1 Quote Link to comment Share on other sites More sharing options...
victoly Posted August 6, 2013 Share Posted August 6, 2013 Oh I am too. However, everyone else in my house runs about 5 degrees hotter than normal humans. 1 Quote Link to comment Share on other sites More sharing options...
bige Posted August 6, 2013 Share Posted August 6, 2013 Your electric bill must be outrageous. I'm not even sure my ac could do that. It runs none stop to stay at 78. Quote Link to comment Share on other sites More sharing options...
victoly Posted August 6, 2013 Share Posted August 6, 2013 It may be, but I'll take an electric bill over a heat-raged-family. 1 Quote Link to comment Share on other sites More sharing options...
