We've had our Eclipse 6 gal
tank for almost 2 months now. We have a platy and a tetra and 8 baby mollies. It's cycled and overall doing well. We are doing 35% PWC
's weekly. The heater is a basic 50 W submersible with a dial on top.
We went away for the weekend, turned the house temp from the usual 70 down to about 62 degrees. Also left the light off since we don't have a timer yet. When we got back lastnight, the platy was sluggish and the water temp had dropped to 70! Now that we have the house temp back to 70, the water has come back up to 74 (so far) and the fish are getting back to normal.
Is there a better kind of heater with a thermostat that would fit our tank that would be able to keep the water temp more accurate despite the drop in the house temp? We don't go away often in the winter, but we'd prefer not to have to heat the whole house just for the fishies! Thanx
