I have switched all our aquariums to the Finnex HGP line. They come in 100, 200 and 300 watts. I have two 300 watt in the 150 tall.
The digital read out can be read from across the room, and the temp adjust is on the end of the power cord. They are very accurate when compared to known accurate thermometers.
Do you have a canister filter? I have a Hydor external inline filter for two years now no problems. Only need one of them.
1 heater of the right size usually works.
The size in watts can vary.
What would be the tank's average target temp, and what would be the coldest ambient temp of the room during the year?
Subtract the lowest room temp from the target tank temp.
There are charts online with a table to match heater size to the corresponding tank size vs temperature differential.
The larger the temperature differential, the larger the required heater is needed for a given size tank.
My 75 gallon tank does just fine with a 250watt heater, but that heater might be inadequate if the tank was in a basement in Michigan during a winter Artic blast.
Let us know the lowest room temp and what temp you want your tank to be at, and on sure some members will give you some suggestions.
As far as brands, I would trust the usual name brands in the fish keeping hobby.
I would stay away from the unknown brands on Amazon, that are half the price as a usual name brand heater. You don't want the thermostat to fail and come home to a cooked tank of fish!
So it's possible the room will go as low as 60f, correct?
What type of stocking of fish were you planning?
Community tropical? Rams? Cichlids?
I'm asking so we can ballpark estimate your target tank temp.
I think it was Cichlidude that has posted the heater table chart I was talking about. Maybe he will chime in and post it, if he has it still.
Well by that table looks like I have more then I need then it should never move from 77.5f if house is at 70f-72f
300 watt Ehiem Jager. Cost about $30 - $35. I've got three of them. Never a problem.
I second the Eheim Jager. It’s all I’ve used for years and they are super reliable.
Probably. But I am here trying to get info on a good heater for a 55g. I'd like something with a long power cord. Not sure what type of filter I'll be running in this tank. It will house 1 juvie fahaka puffer and guppies. House temp stays around 76°f in summer and 68-72°f during winter.Lol, I just realized this was originally posted in March. I'm going to guess he already bought a heater[ ]
