24 nano problems

[YolaKola]

I am getting very frustrated.....I have two problems: First: my 24 gal nano, is doing fine, all my corals, fish are growing, and seem happy....BUT: the temp in the tank is between 80 - 85 degrees.....it's too hot from all the stuff that I've read about water temp....any suggestions? I have all stock equipment that came with the Nano-cube-24

Next problem.....I've got an arrow crab (looks like a huge spider) in the tank, and I think he's eating my fish.....any suggestions???? Thanks Yola

first of all, my tanks are running warm right now 82-85 degrees yesterday and everything is fine. You can replace the stock pump with a maxijet 1200 i believe uses less wattage.
Arrow crabs are not reef safe from what I have read.

bowfront is on the money, maxijets generally run cooler and arrows are not reef safe. additionally, what is your heater temp running at?

[bowfront26]

yah, every heater i have ever had runs warmer than what I set it to

[smy168]

you have to realize that a nano system runs about 3-5 degrees warmer than a system that's 50 gallons so if you keep your heater at 81-82 then lower it to 78-79.
