75 Gallon Tank Heater help.

[DonBaldy]

Not comfortable with the Fluval e300. Just a gut feeling. I know that the temps ( 77 on one end and 75 on the other ) are safe, but it's the face that no matter how much I adjust it higher it stays at that temp.

I went to LFS today and bought an Eheim Jager 300 and HOLY . this thing is taller than my tank by a good 2 inches.

Can someone reccoment a good reliable heater for a standard Marnieland 75 gallon tank?

How tall is the tank?

21 inches

You can setup the heater horizontally; I use hygger but your problem seem to be not comfortable with differential temperature - that can be solved by better flow around the heater or two heaters on each side.

Having said this there is of course some risk as overall heaters are not that reliable ... so it becomes a game of picking your poison. No heater is going to solve the differential problem you described so if that is the only issue you are having it is some what minimal.


If your problem is you want the aquarium 79 and a 300 watt aquarium can only keep it at 77 that is another issue though more details would help like the temperature of the room.

Ambient temperature has quite an effect on what temperature a heater can maintain in a tank & tank size does too - larger volumes of water cool more slowly than small ones.

In my first winter in my new apartment it was way too chilly especially in my room where the small tanks are.

It was getting as low as 14C (52F) at night & around 17-18C (62-64F) on warmer days for a couple of months. Not even goldfish would have enjoyed it though it wouldn’t have killed them.

The heaters I had never shut off because they simply couldn’t get near their set temperature in a room that chilly.

It was necessary to get a much higher wattage heater to get water warm enough for a betta & for the rest of the tanks which didn’t need to be quite as warm, either a higher wattage heater or an extra heater.

Thank you for all of this. I'm still a young back in the fish hobby.

Right now the heater is positioned vertically on the far left of the tank right next to the intake of the FX2. The outflow is just inboard of the intake.

AC temp is never set below 73. Wife and daughter get cold easily.

There had been no lids, but now there's lids as they came in today.

I guess I just want to know if I ever get fish that prefer warmer water that I can accommodate them.

I may also be overthinking it.

A 300w Eheim Jager will maintain 77F in a 75gal if the ambient temp never drops below 71F. It should also have no problem going a few degrees higher if you need it to, though in that case it might be more efficient to have two heaters. For better distribution of heat it might be worth moving the heater more horizontally where it's more exposed to the flow from the outlet.

Btw I find that these heaters usually need calibration with a reliable thermometer. Don't trust the dial setting to be accurate straight out of the box, although you might get lucky. Unlike the newer electronically controlled (e) models these have the old fashioned thermostats. But once calibrated they are very reliable.

I like Finnex Titanium horizontal heaters with in-line temp controls outside the water. With my 65g and 75g, there are two 200w heaters in each tank. Each pair of heaters is powered by a Controller set to a max heat level so my fish don’t ever get cooked should a heater go crazy. Mine have run for years and keep the tank temps consistent.
