We think the ice is okay if it is on the top because there would be ice on the river. The ice will make the water colder. It was good for the teacher to turn the temp up a little to keep the temperature right for the fish. We used to get ice around our cooler too. Some ice is okay but watch out because last year the ice expanded and broke our 20 gallon tank! So we went to a 10 gallon tank that was too small. Now we have a 30 gallon tank.

Here is a math question if we have a 30 gallon tank, how many liters is it? There are approximately 3.79 litres in one US gallon. There are close to 114 litres in 30 gallons. (Geary Elementary School)
