Thank you all for the answers. I was kind of wondering about some of the answers. I have been to Hawaii and the water has been about 76 or so, and I have been to the Keys and the water temp was around 86 so I was wondering why that would be bad in an aquarium. Also the ocean temp changes a degree or two throughout the night. I was able to get my water down to 80 last night. I left the lid open on the canopy to let the heat escape from the lights today. I also set my air at 83 instead of 86. When I get home ill check the temp. I have to take my water to be tested today and hopefully Im ready to add some residents to the tank
Right now its just LR and LS.
This is exactly my point...some critters do need cooler temps like sea horses for example. However most reef fish like the warmer temps. Hobbyist keep a cooler tank to slow down growth so they can keep an eye out if problems happen, like cyano.
A healthy tank has no problems with the warmer temps, the critters like it. However...the smaller the tank the faster things go wrong, and must be addressed. A 55g is a nice size and it grants a little room for error.
Some coral also prefers cooler temps such as Xenia. So read up on any critter you intend to get and make sure they all can live together under the same heat and water needs.
