This is a discussion on Heater and Filter within the Freshwater Aquarium Equipment forums, part of the Beginner Freshwater Aquarium category; -->
I recently purchased a Filter and a heater for my 10 gallon.
The filter reads 250 litres p/h
and the heater reads 55W
That sounds quite good. 250 LPH = 66 GPH, which is pretty good. You want your tank water to pass through the filter at least 4 times per hour. The standard for heating is 5 watts per gallon, so again, you're right on, although it really depends on the temp in your house, if you have a lid, how much heat your light produces, etc.
So i can only know the overall temperature when I actually set it up with water, heater, and lights? If so cool, I should be getting the light in 2 days or so, along with my plants, and start cycling it then.
Will keep you guys updated (on different subforums lol)
