I need a new heater

What is a good reliable brand.

 

I prefer this one.
ViaAqua Titanium Heater

 

Hydor theo is good and cheap

 

I got two in my 75, both are the eheim jager. I got a 100 and a 150 that if one goes bad my tank will still be ok. But they are great!

 

I just bought a finnex titanium one. so far, I really like it. I got a 500 watt unit and it along with 2 other 250's keep my tank at perfect temp with the sump in the garage and sub freezing temps outside. I have about 250 total volume in my system. they will raise the temp from 77.6 to 78.9 in about an hour.

 

I use a Finnex titanium also and like it. Get one with an external controller if you can, they tend to be more accurate.

 

Get the stick and buy a controller.

 

Don't laugh when you see the brand...

Marineland Stealth Pro

I will never buy another heater. You set the thermostat to your desired temp and the clear dial glows red when heating (or auto-shut off from low water level) and green when off (temp is where you want it). The best thing is that I can see the light through the little air slits in the top/back of my BioCube if I'm standing over the tank. I paid about $22 new.

my two eheim jager heaters are also hooked up to my RKL and they are set at 78.9 and never move from that. I have seen it go to 79.0 a few times but they are perfectly stable.
