20 Gal Heater Size

[BklynsBurning]

hI guys

now that its getting colder, I need to replace the heater in my 20 gal tall...I moved it into the garage this year and it gets down to about 50F in there...so I know I need to oversize the heater...any suggestions on wattage?...ideally I need the tank around 76-78F...that would be at least a 25F increase

also need a reliable manufacturer since it is going to be overworked

thanx

I use this Finnex heater in my 55 the 300W and just got a 200W for my 29 once I set it up. It stays at the perfect temp in my 55 and the nice thing about it is you can regulate the temp with a dial on the cord instead of reaching into the tank. I also use Aqueon Pros which I haven't had any problems with.

I have two 20 gallon long aquariums and each has a 100 watt heater and they are perfectly adequate

Here is the table to help with what size individual heater you need. Delta T is the difference from the lowest ambient room temperature in the room to your desired tank temperature. Always get a heater larger than you think you need so just round up to the next nearest size.

I would also recommend two heaters rather than just one. Neither will have to work as hard, and if one fails...

I have a 20 gallon with a 100w Aqueon heater with no issues. Keeps it a steady 76 degrees in my basement here in Michigan. $18.99 on line at Petsmart, double that price in store. In store will match on line price.

I don't know what your budget is, but that Finnex HGP sounds really nice...about $40 for the 200 watt on Amazon.
