Caryl Posted January 31, 2006 Report Share Posted January 31, 2006 I was reading a thread in the saltwater section re how to keep the temp down in the marine tanks on hot days. Got me checking my tanks and I found an interesting (to me) discovery. I would expect the inside tank temps to match the room temp. The ponds could vary due to wind chill but... Lounge temp - 29.5C Tanks in lounge... 4ft community (tank surrounded on all sides except front) 29.5C leopardfish in 3ft tank (metal lid) freestanding 29.5C goldfish in 18" tank open on all sides and near window 32C! The goldfish was in direct sun for a short time early morning but not since. The African tank matched its room temp too - 28C but I have the aircon on now so it should drop. Outside I have one 6ft paddling pool, one water trough slightly smaller but similar height, and half a mussel float for the daphnia. The air temp is 27.5 but was 30.8 earlier in the day. The paddling pool and daphnia float are both 28C but the goldfish pond is still 30.8C. Maybe the fact it is fibreglass means it retains the heat longer. I expected the mussel float to also keep its heat longer as it is black and quite shallow. Since none of the fish (or daphnia) appear to be concerned their temps are up a bit I have not done anything to lower it, like turning off the lights, lifting the lid, running a fan across the surface, or dropping frozen bottles of water into the tank. How are the temps at your place? Quote Link to comment Share on other sites More sharing options...
Grizzly Posted January 31, 2006 Report Share Posted January 31, 2006 well, the temperature never really gets hot inside. outside is usually about 25, so theres no problems. my brother, Herc, keeps his coldwater tank cool by plopping a few ice cubes in it. if its possible to get a draft going in the house it might be worth removing the covers of the tanks, the evaporation actually cools the water quitewell Quote Link to comment Share on other sites More sharing options...
