How many watts?

[turtlesrule101]

how many watts in a heater will I need for a 20 gallon long tank?

Do it on the amount of water in the tank, not the amount the tank holds. Most heaters tell you on them how much water they heat. However, I don't think you'll need a heater. The heat light normally takes care of that, too - especially in such a small tank. Doesn't take much to heat 15 gallons of water.

I wish i could help, i recently got a heater for my 10 gallon but i threw away the papers and box it was in and it doesnt show the watts on the heater itself so i cant help you, sorry
What kind of turtle do u have?

I looked it up for you. You should go with about 100- 150 watt.

I would NOT go that high for a 20 gallon tank (that probably has less than 20 gallons in it)

3 watts per gallon is the normal rule of thumb. 50-60W will be plenty.
