Best heater

I would like everyones opinion of the best heaters you can buy. This is for my sea horse tank so I want the best. Heres what Im looking at so far:

Aquarium Pharmaceuticals RENA SmartHeater

Unless someone can change my mind Im planning on using two of the 50 watt models for my 20 gallon so if one sticks my horses wont cook.

 

Titanium heaters are better IMO. Finnex makes a good one.

 

Ok how about one of these?

Azoo Titanium Heater

 

Looks good.

 

Azoo tends to be on the...lower...end of the quality spectrum. May work perfectly, but with a heater being a pretty critical and inexpensive piece of equipment maybe something to reflect on.

 

Thank you for the input. Im trying to put the best into this tank to make sure my horses survive for years.

 

What brand would you recommend. I was just going off what I saw on one site but Im up for suggestion.

 

I have heard very good things about titanium heaters but I bought them 300 watt Fluval E series heater. It has a digital read out that displays the tanks temperature which can be set to 0.5 degrees. If the temperature is within 2 degrees, the screen is green. If it raises or lowers higher than 2 degrees the screen turns red or blue respectively. I have been very pleased with it and it is nice to turn the corner and know that the temperature is close to where it is supposed to be. Best of luck!!!!

 

That does sound like a very very nice heater. I like the sound of the precision. Ill add that to my list of considerations. Fluval is definately a reputable brand too.

 

Ok now this is the one Im going with until someone changes my mind again.
