Upper temperature limit for sps

fohadi16 · Aug 1, 2022

Hello guys,
So I live in florida and lately it's been so hot my AC can't keep the house below 83 Fahrenheit. I noticed my tank is sitting at 81 currently, I have 2 clowns, for sps I have pocillo, stylo, cyphastrea, and aMonti. I have ordered a cooling fan for the tank but it gets here tomorrow night, is this okay until tomorrow or should I try to cool it off with ice, etc. Thank you in advance!

Any fan can blow across the water. I’m using a pedestal fan that keeps my tank at about 77. I’m not sure how hot it would get without it, but it quickly climbs to 81 without it and is still heating quickly.

In the interim, bottles of frozen RODI can help.

Just a thought.
I lived in Guam for a couple of years. The ambient water temp on the reef tended to hang between 80 and 83 degrees throughout the year. The corals in the Micronesian island group (including SPS) were awesome. As a diver, it was a truly amazing experience for me.

I personally like to keep my reef between 78 and 79 degrees, but occasionally it will climb above 80 due to the room temp. I don't worry too much if the temp goes above my parameters, as long as it doesn't keep climbing.

81 degrees is a little higher than I'm comfortable with just because I don't want conditions to allow temp to keep climbing and get too high. I personally wouldn't take any extreme measures to reduce the temp as long as it's not still rising. I think the fan you have coming will help bring the temp back down to a more acceptable level over time. You'll be surprised how well a simple fan can reduce tank temp.

Again. Just a thought.

Thank you, and that's awesome. When I was in the persian gulf the water temp was around 76 and the corals there were beautiful. I was really worried because I noticed my kenya tree randomly started dropping branches (I know they multiply like that but it was so sudden) I tested water perams and everything was fine so I assumed it was the temp. Anyways thank you for the reply and I will install the fan tomorrow.

Thank you for the reply my friend!
