Amazon and Chewy have Fluval E-series 300-watt Aquarium Heater for $41.99. Recommended for tanks up to 100g.

Amazon [amazon.com]
Chewy [chewy.com]

According to 3camels this is close to the lowest price since 2014 - the regular price is around $50.

From manufacturer's website [fluvalaquatics.com]:
The most technologically advanced aquarium heater available today, Fluval E300 Advanced Electronic Heater, with VueTech technology, delivers peace of mind thanks to several excellent features.
Equipped with an intelligent digital microprocessor monitoring system, with dual temperature sensors, this 300-watt heater continuously monitors and displays aquarium water temperature, ensuring the safety and well-being of your aquarium inhabitants.

------------------------------------

!!!Chance to make the deal even sweeter!!!

If you never used Chewy.com before, you can enjoy their extra 20% discount for autoship order. Autoship can be cancelled at any time.

Suggestion - you can add this heater for $41.99
https://www.chewy.com/fluval-elec.../dp/152099
and Seachem Safe for $7.33
https://www.chewy.com/seachem-saf.../dp/131199 - it is 2c better than the recent FP deal - https://slickdeals.net/f/11274731-8-8oz-seachem-safe-water-conditioner-for-fish-aquariums-7-35

$49.32 order will qualify for free shipping + if you set up an autoship of Seachem Safe e.g. every 16 weeks, it will give a discount of 20% off the whole order, so the total will be ~$40 + tax. You can add other stuff from there (they have more Seachem products available for the same or lower price as Amazon) and get 20% off the whole order up to $15 (so $75 order max).

I am actually replacing Eheim 200W with this one.
There is nothing terribly wrong with my Eheim - it's just a complete pain to calibrate (at least the one I have and its temperature dial seems to be "indicative" at best).

I was debating between Aqueon Pro 250W and this one, but after reading some terrible recent reviews on Aqueon (exploding/killing fish), I crossed it out of my list. Someone at Fishlore suggested looking at this heater, so I monitored it for some time and when the price went down I pulled the trigger.

How big is your tank? I'm setting up a new 125, and was considering the Hydor. I'm just wary of chopping up the hoses on my FX6 to install.

Yes, have to do that. Smilie You can always get extra hose though if you wary of chopping the original. This is a relatively small tank (65 gal) only sand, stones and cichlids. I wanted to avoid looking at another piece of aquarium tech so got the Hydor 300W.

Had one of these, they are VERY finicky unless there is a ton of water flow going over them. It's great if you can get it setup appropriately

I've used this for the past several years without it fail. It has kept my tank heated 84 degrees continuously. In the past few months the LCD portion started to fail and now its almost blank.

Jesus. What are you keeping at that temp?

I'm still unclear how/if there's any type of real controller built into this thing. It claims to have separate pieces that monitor and control temp....but doesn't get into a ton of black and white details on it. So basically the simple question is, can this heater get stuck in the on position? I've bought many brand heaters through my aquarium career and had them all fail in one way or another at some point. If you don't have your heater on a controller, your tank is living on borrowed time. Large temp swings may affect different tanks differently depending on what you're keeping. But coming home to find that my tank is 87 when it's usually 78 is not pleasant. EVEN IF nothing dies (something usually does), it still takes months to recover.

Ive been running an Aqueon Pro 250W for many years and it keeps my tank at a very consistent temp. It is priced very competitively as well and comes with a lifetime warranty, which are reasons why I went with it in the first place.

The Eheim has been popular because it works off a bimetallic strip for mechanical control, which is generally more reliable.

However, for redundancy, consistency, and safety, the best strategy is to couple these heaters with a separate temperature controller:

Definitely worth the extra expense imho...esp for reef tanks.

I wanted to go with exactly that model too and was literally about to press "Place Order" button on Amazon when I saw a recent review with pics of exploded heater, dead fish on a tissue and a heartbreaking story and... sorry, I can't buy it now even if it is priced well. Fu**ed my mind a little bit, I love my fish too much lol. No logic behind this, just pure emotions.

That's my next step, but I want to turn it a bit into a DIY project based on Raspberry Pi or Arduino - I want pretty much the same functionality (relay cutoff if temp goes too high), but I also want to add some more stuff like notification by email and/or another outlet for backup heater etc - still early stages of work in progress, but that's just for fun Smilie

You may be able to recover the LCD with a heat gun and an eraser. Look up LCD fix for calculator.
