Would those temps really cause that serious of a problem for you? I try to keep my 56 gallon tank at that temp, actually. I have two seahorses in the tank, and I don't want them to have problems with bacteria.
No one reads! The low temps are chiefly for the seahorses, as seahorse keepers have found that vibro (a common bacteria, and one that can kill seahorses) multiples and mutates at a much greater rate above 74 degrees than it does below it. Also, my hair algae growth is nil when the tank is down to its lowest temps (69 degrees), without having to cut back on feeding (which, with two seahorses and two mandarins, I do a lot of.)
The tank wouldn't be most people's cup of tea. I have a huge gorgonian; some easy, not very sting-ful LPS; softies like xenia and a very small toadstool; mushrooms and rics. A few not-too-showy inverts (like nass, ceriths, a bigger algae eating snail, a few hermit crabs), two H. erectus seahorses, a pair of mandarins, a naked ocellaris, a blackcap gramma, a Lubbock's fairy wrasse, a pair of copper/red stripe cardinalfish, a coral beauty angelfish, and a citron goby. The naked ocellaris used to be a pair, but then one just disappeared overnight and the next morning one of the dogs had a belly ache.
I just sort of happened upon these seahorses, but want to make the best of it for them. This species is currently being found from FL north to MD, NJ, and NY -- even RI and MA. Historically, they were even found in around Labrador.
My other tanks run a bit warmer than this one, but I don't like to have a normal operating temp that is too high. This house isn't air conditioned, so I need to keep the "normal" temp low just in case the ambient temp would rise during an oppressive heat wave. You can only do so much when the house is 87 degrees....
