This probably isn't necessary, but, well, yeah.

Also with the heater adjustment outside the tank temp adjustments are much easier.

Only a few months in use and already stopped working.

I have a tall 29 gallon that had a typical submersible "stick" heater in it. The problem - inconsistent heat. No matter where you put that stick, the temperature in the tank will vary as you get further away from the stick, and will vary a lot from top to bottom. I had to set it to 82 degrees to get an average of 76, and the furthest corner was usually closer to 72.... that's a HUGE variance which is bad for the fish.

This heats ALL your water - every drop passes through this heater (about 6 times an hour if you have adequate flow through your filter).

I put this in my output line, set it to 78, and within 1 hour got a reading of EXACTLY 78, no matter where I put the thermometer in the tank. I will never go back to stick heaters again.

HIGHEST RECOMMENDATION!!!

Only a few months in use and already stopped working. I'm just lucky I noticed a temp drop and had a backup heater on hand. Buy something else.

My first fish was a little crazy and used to swim frantically around the tank banging into the walls. Turns out he smashed the glass heater and the rest (along with the fish) is history. Went to the "in-line" heater version after that and this heater works great. Use it in a 30 gallon, acrylic tank.

Returned this immediately since it did not work on arrival. I've read too many horror stories about this heater malfunctioning that I didn't bother to try another. A brand new dead heater was enough to tell me these things are not built well.

This is a very risky product. Works well for 3 years or so then suddenly it will fail to operate. I almost lost all my fish. The thermostat broke down and the water temperature rose critically. I do not recommend this product.

I bough one of these heaters during christmas and it crapped out about a week ago. made a crackling like noise for a few days then just died. Ordered a new one and now it's doing the same thing. Heater is hooked up right, I'm not doing anything wrong. Awesome idea, Cheap product. Very disappointed.

I have 3 of these heaters in current use and am buying 3 more as I now have 10 baby turtles and need to add more tanks. Mine are currently being used in a 50gal aquarium and two 70gal stock tanks for turtles. I have tried the in tank tube heaters and the turtles would break them by moving them around in the tank. I also worried about burns from the in tank type heaters. These heaters free up floor space and make cleaning easier. The heaters do an excellent job of keeping the water at 80 degrees and in the 3 years I have had them not once have they failed. My tanks are in my garage so the heaters are required to heat the water in 35 degree weather and work fine. Also with the heater adjustment outside the tank temp adjustments are much easier. They do require a canister type filter as they are installed on the outside inline with the filter water flow. I use magnum 350 canister filters and the heater is installed on the discharge line. I would recommend these to anyone needing a reliable easy to adjust heater.

I bought one of these to use with a Fluval 306 canister filter and 50 gallon tank. Connecting it to the filter was not straight forward since Fluval uses ribbed hoses. I ended up using a clear 5/8" PVC hose from the filter to the intake of the heater and then used the rubber connector and the ribbed hose on the discharge to the tank. So far in nearly 6 months of use this has worked flawlessly with no leaks.

I can't say enough about how well the heater works as far as controlling the tank temperature. I have a digital thermometer and it never fluctuates more than +/- .1 degrees no matter what the room temperature is. You do hear a slight click when the the heater turns on or off which means they use a mechanical relay to control the voltage to the heating element. I like this as most heaters use a solid state relay (think transistor) which is usually the reason heaters fail in the "on" state and fry the tank, SSR's almost always fail "on".

If you have a canister filter you can't go wrong with one of these heaters.
