Is this insanity? I’ve been doing (by accident for months due to a bad thermometer) and everything seems very happy. Does this have any negative effects?

anyone else cold(ish) water reefing? Or am I the only moron…

should I bring the temp up a few degrees if everything is happy?

It's where mine has been for a while. You can certainly bring it up slowly without any issues. There are plenty of successful reefers who keep their water at this temp and some even lower. Changing temp throughout the year, along with other adjustments can actually induce spawning events in our tanks, but it's not a simple process. Just do a search for Rich Ross and spawning.

I've kept mine at 76 for awhile. Didn't see any negative effect. It's now set at 78. I don't want to risk losing corals jumping from 76 to 82 degrees everyday.

76-77 is more than fine. i'd honestly keep mine there if it wasn't so hot where i'm at

people keep their tanks in the low 70s for some fish and it's fine, coral growth is probably a bit slower in general


that tank is almost certainly in the 72-74 range for those fish

76 to 77 is where you want to be! Think of it this way, imagine being outdoors in the bright hot sun on a cool breezy day vs hot day. The bright hot sun being your LEDs, T5s or whatever. If your tank is running at 80 degrees then it's going to have a lot of problems as it is plus then the light source will heat up the corals that much more which can cause them to stress much like our skins burning in the sun, hence, a negative reaction. For soft corals, lower temps help them look better by keeping them tightened in compact form as supposed to it being stretched out in higher temp. When compacted, the corals are more colorful because the skin color pigments are concentrated and overall shape is more beautiful. For example, short thick colorful tentacles on anemones vs long skinny semi colorful tentacles. 78 and 79 is close to 80. This is why I think you should try to keep it between 76 to 77.

A lot of the good things I learned about reefing were through accidents :cry: hahaha. Happy reefing

I have never heard this before. My anamonies would disagree. My tank is at lower temps (76) in the winter and into the 80s in the summer sometimes and they look the same year round.

My tank is at 81 and 82 during the summer and the corals are doing fine. I don't have expensive corals.

Depends what you’re keeping, some of the corals in our tanks like scolys are probably most often found in 72-76 degree waters wheats some other corals may be collected in 80 degree waters or even warmer. It is all about finding the right balance for the animals you want to keep

FYI, I looked up what my temps have been on my apex. In May they were 76-78. Thats as far back as my apex would show me. I also log it when i do water test. but just the temp at the time I check water perameters in the evenings.(warmest time typicly In december i recorder 76.3. My first heater is set to come on at 76.6 but it is not enought to keep the tank that warm. The second is set for 76.0. I have 2 addtional not on my apex as i don't trust it anymore. They are set at 75 and 74. They will only come on on very cold days or if the first 2 or apex were to fail.
I know it is a bit of over kill, but heaters are known fail pretty often!

I have a most soft coral tank with a couple fish. We were away on a trip and our monster bunnie mowed off every cord in the house and the heater cord to the tank. My tank dropped to 60degrees. Granted that drop took time like 2weeks I guess. Anyhow I dropped in a new heater and raised it 20 degrees in a day. I only had damage to one coral. This green tall leathery coral thing seems to turn black at the base fell over and kind of rotted. I removed it cut off the rot and it’s doing fine. Everything else came back on it’s own.. the bubble mushrooms shrunk from the size of a half dollar to the size of a pencil eraser but they too all came back. I think I got lucky, but I think some of this stuff is hardier than we assume.

How did your Apex fail? Wow, never heard of that one. Do you mean the probe went bad? Great looking anemones by the way!

1. It failed by switching my kalk dosing pump from auto to ON. I did it 3 times. The first time i thought i had accidently done it somehow, as I had made some other adjustments a day or 2 before i realized it. Luckily my kalk container was not very full that time. The next ywo time i had not touched it for at least a week before it switched it to on again.
2. The second failure is it failed to send my alarms when my PH spiked way above the point it was set to notify me.
3. My display abruptly quit causing the brain to shut down.
4. EB8 brain shorted out.
All these components are seperated from my sump area and humidity. They have never gotten wet. I use electrical grease to give all conections extra protection from moisture.
Thank you. I have Rose, Rainbow and purple rain anemones.

Wow, the Apex operating system should not have allowed the dosing pump to switch from Auto to On. It's strange to see that it happened again. I can see how the email notification alert can help people, I've never been able to figure out how to use that function, hahaha. It sounds like you had a lot of problems with the Apex. That's unfortunate. I think the biggest problem I had with mine is the salinity probe kept giving me bad readings. I'm on my 3rd probe now. Do you run yours on the local network or the other one (non-local)? The guys over at Apex told me to run it on the local network; they said something about the reliability and connection is much stronger but I'm not sure how that would have helped in your case. I figured, it would probably be better for you either way.

Sorry for the late reply.
