my mums being a pain and wont let me get a bigger tank because she tinks it will cost more. dose it actually cost more for a higher watt heater because i know it will cost more when its on but wont it be on for less time
generally yes a bigger tank does mean higher costs, however if you select the hardware carefully then it doesn't have to cost a lot more, for example if you went for an air driven filter then you would most likely use a lot less than if you use another type
what lights, heater and filter etc are you currently running on your existing tank?
well i want to upgrad my 13l and 5g tank the little one dosnt have a light and the bigger one has a 40w light and i dont know about fillter and they have the little tank has a a 25 w and the 5g tank has a 50w heaters in them and i want to change them for 1 100w heater so i can get a bigger tank. and move the fish from them two tank into my 14g and put the fish from the 14g into the new tank. i dont know about the filter and heater and light ill wait and see what tank i get first
