Can 1 degree effect corals a lot?

Can 1 degree change in temperature effect corals a lot? Or not really that much. In general, I know theres many different corals, some more sensitive than others.

I have temp swings and doesn't seem to affect much but its always better to keep stuff as stable as possible

That depends. If you are on the high or low end of the scale it could be detrimental. I had a 6yr tank crash after 5 days at 82. Everything died!

Some corals can tolerate temps up to 104f for a while. But it doesn't last long. 1f increase depends where it was before. 88f is about the max.

1 degree swing is typical in aquariums that have heaters without controllers. I think it's fine as long as you are within the acceptable range like everyone else stated.

Thanks for the responses guys, I setup a sump with 2 tanks connected and I'm getting different temps for all 3 places. And my it doesnt seem to want to stabilize. It fluctuates between 76-78 degrees. The heater is in the sump

If the sump is centralized and water flow is at least a few times tank size it may honestly be the measuring devices. After installing a basement sump I ran into a similar issue, I purchased a temp calibrated device and found out I was chasing ghosts. How do you measure each tank, same device?

Not at all.

WOW. In the summer in my previous tank, I used to keep my tank at 82+ every day. My corals must have been adjusted to the high temps.

Wasn’t caused by 82. I live in South Florida and my tank runs about 81-82 all year. I’ve had tanks run at 85 in the summer in Virginia. Something else caused your tank to die.

I have my APEX turn the heater on at 77F and off at 79F to cut down on the amount of switching. But even with those swings I’ve never had issues.

I could try upping the gph. I guess that could be the issue, I'm scared of overflowing lol.. I only have 1 probe atm so I just dip it in each tank for a few min and get the reading

Affect .... and no!

 

[Fred2482]

I wouldn't up the flow more than needed to troubleshoot the temp. I would just assume it is already turning the tank over a couple times per hour?

No. I dont think anyone can hold say 78°+- 0°.
Mine runs 77 -79 in the winter, only time I run a heater. Summer it runs 78-81 just running the ac at 78.
The ocean can fluctuate more than 1° too depending on time of day and where you are.
