my water temp in my reef tank is always like low 80's. Is this ok. And also i picked up a piece of coral that literally smelled like sh^^t. Should i take it out?
Depending on how well your reef is running before you put in that LR. All that will happen is you'll get a ammonia spike then nitrite then nitrate. The smell just means the store didn't cure it. They really shouldn't have sold it to you without you nowing this. You might get a little algea bloom too. You could also cure it in another container of water but will need a powerhead and skimmer in it.
