I can't help but wonder. Which heater does everyone feel is the most reliable?
@Ryanbrs . i am surprised by your choice to use both a uv filter and ozone. a uv bulb when properly powered does create safe levels of ozone through reaction with sea water . I think you may be complicating the build for the sps tank without needing to. Also the uv light does break down large chain molecules along with some organics so that they can be removed by the skimmer. I have always used a large uv light with any tank that was reliant on a skimmer for filtration. I learned that from @Boomer years and years ago.
I think this is a trick question.
Based on a previous BRStv segment it was stated that the Colbalt heaters had the most accurate temperature and was also recommended to hook it up to a controller because these hobby heaters are made so cheaply. Going with the ULM theory then you would need two of these hooked-up to a controller. Again in another one of your BRStv segments you can buy a controller starting at 120 bucks. So it is low cost we are looking at or truly a ULM system? Not sure you can have both as some redundancy will cost a few bucks extra.
I will also assume when you want ULM you also are asking for stability, I would think that stability would also give you ULM as well.
I would be interested in how consistent they are.@Ryanbrs for my new reef tank, I purchased two Eheim ThermoPreset heater.
Even if I will hook them up to a temp controller, it seems like a good solution for a plug it and forget it ULM tank as the temp is electronically controlled to be 25C / 77F

LOL, they are the most accurate and precise but also far from free. If you wanted to use two of these to back up a standard tank you would be into it for nearly $300 without a controller.
Since heaters fail so many people my best pulse is a combination of what the CS team says combined with the reviews. Always nice to hear what the larger community's experiences are.
So if I was starting a new tank and was a newbie at this, what advice would you give me? Buy the the Cobalt or in your option what is the next best thing? I like to get insight into those that have had reefs for a long time, knowing that they spent quite bit of money on corals and fish.
I do appreciate your input. No baiting, just asking for advice
How do you find room for 4 heaters and two pumps, esp. on tanks as small as these? *boggle* I feel like I barely have enough room already for two heaters and one pump in the ~30 gallon sump I have. (middle is a big fuge)I'd build in redundancy. I found controllers that can control up to 4 1000 watt heaters. Smaller versions are also available (http://www.jehmco.com/html/temperature_controller.html). So, all of the heaters are on simultaneously and thus they are all used equally and no single one is overtaxed. If you choose the heaters sufficiently large, losing one will not affect things. Not sure how to detect if one fails, though maybe the current draw can be monitored.
For pumps I'd do something similar... use multiple controllable DC pumps each turned down. So if one fails, all you have to do is turn the others up until you get a replacement.
So there are a lot of approaches, and peoples opinions differ, but my opinion is you should have one heater which is fully capable of heating your tank on its own to ~78 degrees. If you have a large tank it might be a pair of heaters. This heater or heaters will be responsible for cycling on and off thousands of times a day and likely millions of times a year to maintain the tank temperature.
Now, this heater will fail, could be 6 months could be 36 months, but it will very often be between 12 and 24 months. That's why we add redundancy with a backup heater. I think it should be the same size and very similar solution to the primary and it should be set to ~77 degrees which is one degree lower. This means the heater will basically never be used and hopefully perform like new when you need it.
Now a lot of us have taken a different approach which is two heaters set to the same temp designed to limit negative effects a failure meaning if one fails on or off the tank won't heat up as fast or drop as low. This is certainly better than a single point of failure with just one heater but really a "less worse" or partial solution. It's also less likely to work when you need it because both heaters are cycling that same million(s) of times a year and likely to fail around the same time. If I did it this way, I might use different brands of heaters to reduce that risk.
In either case, a temperature controller is an absolute must-have for anyone who uses a heater and wants to have their tank last more than a couple years. There are not many things I would say are 100% necessary, but this is one of them. The ink bird is $39 and there just isn't a reason not to use one other than I literally don't have the $39. If that's the case so be it but that should be the only reason. There are of course more expensive and capable solutions like the reefkeeper and apex. At this point, there isn't a universe where I wouldn't personally use one of those two options because I have a lot invested in my tanks. Most often I use the apex just because it actually lets me know "in real time" when something failed.
As to cheap heaters verses the Neotherm? Well, it is 3 x the cost so I would only spend that to achieve a specific goal. I would also only use it on a tank that has the potential to benefit from that. In this case that could be a SPS tank which almost always benefits from every effort put towards stability. The goal would be accuracy, precision and redundnacy. In this case, I would actually use the internal thermostat on the heater to control the tanks temperature and the aquarium or temp controller to back it up. The benefit here is the we don't have to power cycle the entire heater millions of times a year which is certainly not good for it.
Hope that helps , I got a bit more on this in this weeks video update.
