I have a 5.5 tank... would it be okay to purchase a 30 watt heater? Here is the description:
"The HT-10 submersible heater is suitable for aquariums up to 30 gallons in size. The electronic thermostat automatically adjusts heat output to keep the water at a constant 78 degrees F
. All you have to do is place in the aquarium and plug it in."
I know someone told me that for a 5.5g tank a 10-25 watt is suitable... so would it matter much buying 30w? Please help
(I'm thinking of ordering online. I have no real fish stores near me, and I don't drive :P)
