temperature

Hello, long time lurker but just started my first reef tank a week ago. I’ve been in the freshwater hobby for over 5 years and just recently made the jump I’ve been dreaming of. I am asking this question for a few reasons: 1. I’ve seen different threads on here with very different opinions...

When I was taught the basics a couple years back I was told 76°F was the only acceptable temperature for a reef tank, so that’s what I’ve kept my tank at this whole time. However, the guy who trained me at that previous LFS job was very set in his ways. I often hear 78°F is the best, so I’m...

Hi everyone — I’m building a DIY reef controller using an ESP32-S3 and could use some guidance from anyone with electrical/analog experience. pH measurement (Main Question) I’m trying to design a safe, robust pH input circuit that interfaces cleanly with the ESP32-S3 ADC, but I’m a bit lost on...

I am setting up a tank that will run slightly cooler and I aim to have a daily temp fluctuation of around 72-75 degrees. What corals would be happy living in these conditions? I am looking to go more soft and lps heavy, and I especially like the euphyllia and leather corals, but I would like a...

I have two inkbirds and they have a 4 degree difference so I need a thermometer to calibrate them. Does anyone use a candy thermometer to check there tank? Or should I buy the Hanna thermometer since those seem highly recommended?

L for some help. I added a Pentair 18w UV to my tank to help fight Dino’s. The water and stuff looks good now after running it but it’s causing huge temperature issues. I was told to run 24/7 which is fine other than my temp steadily increasing. I went from 78 to almost 82 in 24 hours. Had to...

I have a new setup running reef pi 6.0 on a pi 3b+ The Heater Threshold field runs my macro which sends an email alert. I get the message when the probe measures higher than the value. And opposite, the chiller threshold is activating when the probe measures a low temperature. The GUI won't let...

Thanks in advance for any feedback. I have a 4 mo old 75 gal reef with a 30 gal sump. I'm in Florida, I run the house at a cool 75 all day long but I can't go much cooler than that. I want to grow corals, inverts and fish. My temp fluctuates from 81.8 during the day down to 79.4 at night...

I have a Fluval Evo 13.5g and the eshopps nano skimmer pump is producing too much heat for a stable temp even when my heater is turned off. I need suggestions for a cooling fan or system, ideally that would fit in the empty chamber of my filtration compartment on the side (9cm x 7cm x 1ft).

I live in Italy, where summers are very hot and electricity much more expensive than the US. I'm gonna be keeping either Kuda or Erectus seahorses, so, despite the cost, I'm having to set up a chiller. What's the hottest temperature I can run a seahorse tank without risking infections or...

I'm very much new to reef aquarium, currently thinking of 4 clowns, 2 blood red's, a couple of hermit crabs and one or two anemones/bubble tip ones for my 20g tank. So, do the common clownfish,anemones,shrimps require chillers ? like in my country it gets 30c / 86f in the summer. Not interested...

My temp stays at 79-82 without a heater. My house thermostat is set to 72. Does this sound right or is it way off? I have a 90 gallon with a 20 gallon sump. Is my equipment putting out that much heat? Here’s what I have: Display: ATI 6 bulb T5 2 jebao SOW-15 Sump: Sedra pump (for euro reef...

I know this is going to be controversial… I have a 13.5 Fluval and I’ve been running it at about 82 degrees. I’ve read that this can help cut down Dino’s growth. It seems to be helping. Any idea what long term effects of this increased temp may be? The corals seem fine but I could be doing...

I currently keep my tank between 78-79 (use a heater and a chiller to consistently keep that 1 degree difference). I just got scolymias and I heard various people say keep the tank between 77-78, but others say that 78-79 will be fine as long as it's consistent. What is everyone's thoughts?

I don’t know what’s going on my tank is reaching 89 degrees and I have 4 fans the back is open I have a bubbler and a wave maker I don’t know why it’s a 75 gallon tank

Hi All, Has anyone tried using a tankless water heater (Just like a chiller would work) for tank temp management with low set point? Any thoughts please.

My grouper has been rubbing himself on the sand and he has been eating quite well also he has this mark I thought at first was just his coloring it’s not identical to the other side hes hard to tell I was thinking the temperature because I have a glass lid heat gets trapped so it gets hot like...

So I have just a general question. I haven’t been able to find anything out on this. I know about cycling,flow, light, no light, skimming, time and the stages etc… my question is: does temperature play any role or have any affect on the quality of the bacteria and the quality of the cycle...

I was researching coral shipping and temperatures and so on and came across this older thread: https://www.reef2reef.com/threads/heat-pack-study.96954/ It seems to be the only one I've seen with data on temperatures over several hours in the cold simulating shipping. I would love to see any and...

Hello fellow reefers and freshwater aquarists! After years of development and testing I finally made up my mind to introduce to you my AquariOS controller project, intending to use this thread as its long-term support platform. It's about a 20-channel low-cost DIY aquarium controller, capable...

Hello! Marine lights are generally rather pricey. Anyone ever considered light therapy lights? They seem close to the right brightness and color temperature? Any opinions? TIA!

Just want to say this first, I am not an experienced reef keeper and am not looking to keep this fish, just looking for information because it is interesting to me. I live in Australia and was reading about the Lennardi wrasse which apparently likes much cooler temperatures than most reef tanks...

I am new to the forum, and I need some advice. I have a Fluval EVO 13.5, and it is FOWLR. It is cycled for about two weeks now, and I was thinking of starting a reef in October or early November. Now here are some questions I have before I convert the EVO to a reef: • I live in a rented...

What does everyone out there use to calibrate your temperature controller? This all started because I noticed my Hanna salinity checker is consistently 1 degree below what my controllers say. Here are my options: The controller itself. Cheap glass thermometer that came with a 20g tank: 72...
