Advice: Unhappy tank..

[Beverly]

While 80-81 isn't really hot, I keep my tanks at around 78F in the event ambient room temps raise tank temps. Also, I make sure there is lots of surface agitation for good gas exchange allowing for maximum O2 in the water. SG is 1.025 to 1.026 which is maintained by adding RO/DI water daily to make up for evaporation because of the high surface agitation.
