The Ideal Reef Tank Temperature & Why You Should Care

[@VictorAGomez-j8b]

I love your tank and aquascape.

[@viking_reefing]

Good stuff mate. One interesting thing about temperature is that you can manipulate the metabolism of the animals by lowering it which can help with fish that needs to be fed often.

Thank you for mentioning the temp swings that happen in nature. I went from just using my apex to control my heater to using a redundant system of an Inkbird plugged into my apex for safety and less wear and tear on the apex relay. The thing is with just the apex I could keep a much tighter temp swing. Only a .5 degree swing, or less if I wanted to with the apex. With the inkbird the best I can do is a 1.5 to 2 degree swings. This has been bothering me even though everything is doing well. Now I feel better based on your info. Thank you. 75.8-77.2 is what I’m at now and on average. Give or take a few tenths.

I think those temperatures will be fine, as you're seeing in your tank! I was really surprised that some wild reefs do just fine with 6F degree swings - you'd catch a lot of flak on Reef2Reef I'm sure with a swing that big. I honestly didn't think coral would survive that, given how many papers are out that say a 1 or 2 Celsius degree increase in water temperature will likely mean the end of reefs as we know them. That's the difference between a temporary increase and a long term one for sure!

Great video vary helpful im trying to learn as much as I can only thing I can keep alive in my tank is fish Every time I try corals it’s a waste of money so now I’m working on water quality.

[@ReefMan]

Water quality is for sure the most important thing with corals. If you’re having trouble I’d recommend doing an ICP test of some sort to see what might be in the water beyond things you’ve already tested for.

The temperatures in our reef tanks should vary slightly throughout the day. 76F to 80 F slow ebbs and flows probably are normal.

What size tank is that behind you I like it want one with a corner overflow

[@fernandosalazar730]

What heater do you recommend? For a 20 high

Is it risky to have corals shipped during winter ? Would it be better to wait until Spring to buy corals online ?

[@ReefMan]

I think it really comes down to the person shipping the coral. If it's cold outside, it should be sent in a cooler with at least one or two heat packs. If you're expecting a lot of snow, maybe hold off though - any weather that might delay your package could doom the corals inside it. On the other hand, shipping when it's very hot outside could also be bad.. responsible shippers know what they're doing though and I'd trust their judgement. I'd also look for a guarantee that things will arrive in good condition & alive.

not at all

Funny I was just thinking about my aquarium temperature before I saw ths notification. I have always run at 78 and now that I'm trying to let in more fresh air for PH control, I was thinking about energy savings from going a little cooler in the winter months. One concern I have is that if I have a power outage, stating at a lower temperature would be less ideal in winter months. I have backups for air pumps and a water pump but none for heaters. I have heard some folks change their Temps seasonally to save electricity and I have heard of some folks doing the opposite for a little bit of a failsafe, running hotter in the winter and colder in the summer. Do you run your temperature the same year round?

[@ReefMan]

I use the same temperature all year because that’s what wild reefs generally experience near the equator. They’re adapted to pretty stable water temperatures.

[@rja9784]

Soooo you’re telling me there’s not a correct temperature gotcha

[@ReefMan]

It’s a range of correct temperatures. Oceans change just like anywhere on the earth. There’s no one correct temperature.

[@PepeCoinMania]

most of tanks does not need a heater at all
