Is it okay to have the aquarium heater right under the filter?


Question by chocolate: Is it okay to have the aquarium heater right under the filter?
I have an EHEIM jager heater (fully submersible) and an aquaclear 110 filter. Is it okay to have the heater just a few inches under the filter or does it have to be away from the water flow?

Best answer:

Answer by Cally
I have my heater right next to the filter, and it doesn’t hurt anything. I think that it’s good to have it there that way the heater will heat the strain water flow. Just make sure to have the heater far from the thermometer if you have one.

Question by Yuval S: Is it safe to use an aquarium heater with a foot massager tub (while feet are in it)?
it’s a bummer when you put your feet in the massage tub and after 3 minutes it’s getting too cold. Would be nice if I could put an aquarium heater inside to keep it warm for longer. Only questions is – are they reasoned safe for such purpose?… Thanks, Yuval

How do I tell if my aquarium heater is submersible?

by roens


Question by Robert Hersey: How do I tell if my aquarium heater is submersible?
I have an older heater, and some of the penning is missing on it. It’s not too old, it’s definitely still usable. My question is this- How tin I tell if it is submersible? Are there any key features?

Best answer:

Answer by Ben
Submersible heaters are usually “streamlined” and generally either entirely encased in rubber/plastic or have a rubber top with a glazing cylinder containing the heat element. They usually employ suction cups to stick to the tank underwater. They usually have a small knob on top to adjust the temp.Non-submersible heaters are usually made to hang/clip on the side of the tank with only the glass tube submerged.

Question by Tabitha: How long before aquarium heater is supposed to work?
I just bought a Tetra Aquatic Reptile heater for my turtle’s 20 gallon tank but it’s not seeming to heat the tank at all. It’s been plugged in and in there for almost 5 hrs and it doesn’t seem to be working yet. Has anyone had one of these before? And how quick did it start to work?

Best answer:

Answer by Hard K
Trust me it isnt gonna work i had one of those if its the one that you put the suction cups to the bottom of the tank and it has something that you open it isnt gonna work. Go get another one or get 2 heat lamps with 60 watt bulbs. I traded the heater back to the petstore and they gave me a heat lamp for it with a crayfish. Sorry for your lose!
