I was curious as to recommendations for what wattage and how many for a 112g with a sump approximately 30g. Thanks.
Question by: Joel Rodriguez on Jan 28, 2018, 8:14 AM
A single 300w heater should work, but there are a few other factors that could come into play, like ambient temperature, and airflow around the aquarium. In almost all cases we will suggest using two smaller heaters over one large one. Two 200w heaters would be perfect for your tank if you decide to go that route.

Hi Bulk Reef Supply Team,
I am a new reefer. I have a 16 gallon biocube. I have a heater but it looks like it is on its last leg. I am going to take advantage of the black Friday sale.
My question is:
My coralife biocube talk is 16 gallons -- should I go with the 50w or 75w heater? Would you recommend the Jager Trutemp aquarium heater for my tank?
Thank you again,
Victoria

Hi Victoria, thanks for reaching out!
A 75 watt heater would be perfect for your tank and the Eheim Jagers are one of our favorites. The only reason I would say to go with the 50 watt model (9" long) would be if the 75 watt at 10.2" is too big for the back chamber of your tank.
I hope this helps! Let us know if you have any other questions.

Hey guys....I want to buy a heater for my 65 gallon tank but space is an issue since my sump does not accommodate anything of the size heater I need. Would placing the heater inside the overflow box work?
Thanx.

Thanx.

Question by: Miguel Zavala on Nov 16, 2017, 11:13 PM
You can definitely place a heater in your overflow. Their are two things to consider though before doing so, and that is to make sure the heater is always submerged in water. The other is that depending on your flow, the heater may heat up the water in the overflow faster than it can flow out and heat the rest of your aquarium. If you are using a controller with a temp probe, that should not be an issue since you can place the probe in your sump, but if you don't just use a simple thermometer to monitor the temperature in the display tank to make sure it is mirroring the settings on heater.

I bought one for my 6 gallon JBJ. I'm having issues fitting it in. Can the heater be touching anything in the aquarium?
Question by: Jessica on Jan 25, 2017, 8:02 PM
Hey there, great question! Most acrylic tanks can stand up to the intermittent powering of the heater, as far as not melting. With glass tanks and baffles, there is no issue at all with the heater touching those edges. :-)

Hi there - I'm trying to decide between these and the Finnex heating element (both would be hooked up to Apex) - and wondering why the wattage ratings are so different? For instance, the 300watt of this version is rated for a 250+ gallon tank, whereas the Finnex calls for 800 watts for the same size tank. Watts would seem to be watts, so just wondering if these are that much more efficient than the titanium versions? These would be going on a 500+ gallon total system, so trying to be as efficient as possible. Thanks, Peter
Question by: Peter Tucker on Jan 24, 2017, 10:41 PM
Great question! It will definitely tank more than a single 300W heater for that size of tank, so in the mindset of efficiency, you will want to look at the 800W heaters. I would recommend at least 2-3 heaters for redundancy and efficient heating. :-)

Hi,
I want to purchase a water heater for my RODI water while being mixed with salt in preparation for a water change. In other words to throw in the bucket for QUICK heating. What heater is best for that? Thanks

Question by: Reggie on Dec 5, 2016, 9:48 AM
Great question! For the purposes of quickly heating your water, the larger the heater the faster the process. In which case, if you have room for larger heaters then get the largest that will fit. :-)

Hi, I'm planning on buying 2 of these heaters. 1 will be my backup incase first one fails. What wattage should i get for a 120 gallon tank 48" x24" x24"?
Question by: Brian Beaulieu on Feb 3, 2016, 3:01 PM
Great question!
You will want a minimum of 2.5 watts per gallon up to 5 watts per gallon. Overall on a 120 gallon you will need a minimum of 300 watt heater. Feel free to let us know if you have any further questions!
