Will the 50w heat a 30 gallon tank and maintain at 75/80 degree?

I was not able to get it to heat a 20 gal or a 10 gal, so I have it in a 5 gal tank and it still doesn't heat to the level it states it will. I put it in a smaller tank with some fish that don't have to have the water temperature to be maintained at over 75, so it's working find in that situation. I suggest getting a submersible heater that allows you to adjust the heat to the temperature you want, that's what I now have in both of my larger tanks now and I was very disappointed when this one wouldn't/couldn't keep up with at least a 10 gal tank. Good Luck!

I can't say for sure but I have it in a 100 gallon system in a basement and it keeps it at 70 degrees with no trouble. I would get one, if it can't keep up grab a second one.

100watt would be plenty. I have one in my 50gal tank and it easily keeps the tank at 78 degrees. Just as my 300watt keeps my 120gal at the same temp without difficulty. Hope this helps!

Yes. Though it all depends on your ambient room temperature. I had a 29 gal Puget Sound aquarium and was able to maintain a 55 deg temp at a 75deg room temp.

I use the 50watt in my betta tanks. (One gallon) and since its preset it shouldn't be to hot.

Yes. We have our heater installed on a 30 gallon tank and works just fine. A GREAT HEATER

Yes, I have it heating a 2.5 gallon. Do not use in a tank BIGGER than 10 gallons. ( it's made to heat anything from a 1 gallon to a 10, nothing more)

I have a 30 gallon nano and use the 300 watt version, I think I could have gone with the 200 because I have to keep the temp setting around 74 to keep it around 80 degrees....so it definitely runs hot

My measurements and calculations predict that the water around this 50 W heater will freeze at about 11°F. If you want to prevent freezing to lower temperatures, replace the heater with the 80W version, Model 9001. I would expect that one to work to -2°F.

Not sure since I use the container inside where the temp does not exceed 80 degree. However, the tank is very sturdy and I would be very comfortable using it outdoors in higher temps.

I had this heater in a 3 gal 360 tank and it kept it too warm. I ended up buying a heater that I could set the temperature.

I use two of these in a1500 gal tank. We are in northern Ga so far is has maintained this tank to 70° I bought a thermostat to control temp works well does not run all the time

I have a 46 gallon cichlid tank and I bought a 300 watt heater. With the adjustable temperature control, I am able to keep it at a steady 78.4 degrees.

The 50w model was designed for 6.6-15.8g aquariums. The full list of their heaters is listed here: https://www.eheim.com/resources/product//450/downloads/11/EHEIM_aquarium_heater_25_-_300_manual.pdf

I have a 30 gallon tank and it maintains 64 degrees like a charm. I would guess that even lower temps are very achievable.

50W will be cooler, and 75W will be warmer. I don't know what slider turtles need, so suggest start with the warmer 75W lamp, and watch if your turtle gets up close to it, or if she stays back from it. If she stays back, then either raise the lamp higher, or use the cooler 50W.

3/4" should be just fine, it is not up to code, and you will get less than the listed power, but it will work fine to replace an 80 gal storage tank.It takes 52K BTU to heat 80 gallons by 77 degrees, with a 70% efficient water heater. With a 'first hour' rating of 120 gallons it is 78K BTUYou can get 79K BTU at the end of 100' of 3/4" pipe (or equal, with fittings). Code for this heater would require 1" for a run of more than 10'As a note, the efficiency listed is a best case running full power.
