I believe titanium doesn't corrode for all practical purposes and in reality although it may technically be possible. I run a titanium heater, as do many others, and they don't corrode.
Thank you!

Really how many eheims have you gone through ? I have 3 eheim heaters. A 150 200 and 300w in three tabks. And theyre very accurate and work well in my experience anyway
In the last 6 years I've had 5 leak and Two failed and were replaced under warranty. I inspect them regularly and if there is any moisture inside, they come out of the tank even if still working. . I finally gave up on glass heaters with thermostats because just not worth the risk. My finnex titanium have been incredible the last two years.
Yup I spoke to support yesterday and they had me do that. I sent them a video of how I can’t calibrate correctly and they said that was how it works. You can’t calibrate in tenths unless calibrating over 1 degree. Didn’t make sense to me but it has been running stable for a day now.
This is a bummer to hear. I really liked the design of the Cobalts and I'm running 2x 200w wands in my 75g and now that I have them dialed in with my Control4 they seem to hold the temp pretty stable between 78.5 and 79. Prior to the use of the controller the Cobalt thermostat/dial really sucked holding a stable temp and trying to control them individually was near impossible without the controller.
I liked the design of the cobalt being flat with more surface area to heat. And this was a few years ago. I had a bunch of people say all heaters fail and because of that why they went with cheaper options. And for stable temps within 2 degrees, the ocean is not that stable, so... But, I had fire and vigor at that time, “not these heaters”, “you obviously did not spend enough”, mine are way more expensive than what you are using and I won’t have a prob... oh dang it failed, lol. So here we are again, but I’m on a different side of the discussion
. I have titanium ones now. I may try that combo just mentioned with the ink bird, I sent one of those to my sister and she has not had any problems.
Playing Russian roulette putting any kind of Amazon China product in your tank, I had a Amazon vivosun power head I used to mixed up new saltwater and didn’t realize the rotor started to rust until I lost all my acro colonies in my tank...lesson learnedNot attempting to hijack this thread at all!
I have had great success with these titanium heaters and Inkbird combo. I run two 300w in every tank.
My tanks that are in interior conditioned space run a flat line temp history. My tank in the uninsulated basement with propane wall heater varies by 1 - 1.5 degrees.
That being said, I'm a big believer in titanium heaters, and there's no reason in today's technology to still be using mechanical strip thermostats or mechanical contacts. That's 1940s garbage.
Here's the variation I get when my refugium lights and UV shut off at dawn. The rest of the day looks like a flatline.
These are the valuable pieces of advice that keep me coming back to R2R!
