Anybody have any good suggestions for a new aquarium heater. One of mine when out and I need to get a new one..........I have a 125 gallon tank. Thanks!

Aqueon pro or jager would be my recommendation. I use both and never have had any issue

Use a basic Finnex titanium heating element ran by a controller, run two heaters a two degree apart.

Eheim jagger. Been using them for 17 years and still have the first I bought. I currently own around 8 of them and have never had one fail.

Hate to revive an old thread, but lets talk heaters again. Looking into heaters for my 180 and I'm finding that manufacturers specs on their heaters vary greatly from one to another. For example...
I was looking a 300w Cobalt and it had a max tank size listed at 80 gallons. With their recommendations, I would need no less than 4 heaters (I run backups). Now, looking at the Eheim 300w, their recommended tank size is listed 159-264 gallon tanks. I would only need 2 based on their recommendations. Why such a huge difference between the two? I'm assuming it has to do with the heating element that's used in each, but I'm not certain. For those of you running tanks around my size, what are you using?

I run a 1K heater with 500W back up Titanium is the only way to go.

I too wonder how heater manufacturers rate their heaters. When my 300g was on its own sump i only used one 300watt heater made by Aquatop. I still use that same heater in my 100g sump and i keep it set at 80

Using the old 3W per gallon methodology seems it would no longer apply after reviewing some of these heaters. I'm definitely leaning more towards the titanium heaters. I was eyeballing a few from Finnex, but after looking at their warranty, I don't know that I really want to use them. They only have a 180 day warranty and almost everyone else is at 3 years. A little off topic, but relevant nonetheless. Now, some of these heaters require a separate controller to regulate the temp. Anyone have experience with those? Not sure what the benefit of running an external controller for temp regulation is... The expense is a lot higher it seems and it doesn't look like it would be worth the additional money. I'm just not seeing the benefit there.

Not sure about the ones that require controller hook up but I like having a controller even with my heaters that have their own thermostat. Added redundancy in case the heater gets stuck in the on position, if the temp gers too high the controller kills power to the heater

Anyone have experience with the Catalina brand heaters?

Probably looking at just the heater replacement element. You can get them separate or with the external controller that runs the heater. I plug mine into my AC Jr and just use the external controller as a remote temp gauge.

I believe it is all about surface area and turbulence. I had to run 4x 300w heaters on my 150g sump and two 60g frag tanks. Anything less and my temps were low even though my house is never less than 70 degrees.

I think it's a matter of BTUs overcoming heat loss caused by many different factors

Here's how I figured out how many heaters to use on my 5 flat, 2 sump system

Does the formula include surface area?

It does, but only for a livestock free tank. You have to decrease final value by .468935718% for every 1.425" of "fish" to account for their naturally produced body heat

Does that change for more active fish or ones that just sit there. The decomposition of organic material (uneaten food and fish poo) could also cause a slight elevation in temperature by .459867 deg (f) per mg. Celsius is .033742 per mg

Only if feeding flake food or if you have a tank that is prone to breaking at 95 degrees imagined tank temp

That temp could be achieved through overuse of pumps. Pumps= friction
Friction = heat..

Friction = heat

This only applies if rhe BMI of all parties involved is above 28% each

Redneck_Reefer

So BMI = BTUs then.
