Can only one heater be used for this tank or does it require three to heat the tank?

I don't really know I didn't use a heater but I would say 1. The tank is pretty small.

If there is complete separation between each compartment, you might need a heater. If you are going to only keep Bettas, you might not need a heater at all, as long as the temperature in the room doesn't get too cold.

1 heater is perfect cause it is a small tank. More then one would just crowd the space

Its an amazing pump but I would not recommend it be used in conjunction with a tank less heater, these heater require a minimum of .5 gals per min. to activate so it wont work.

There's multiple sizes selectable here. I prefer yo run two undersized heaters so if the thermostat goes bad i in one it won't cook the fish. For a 39 gallon I'd think you'd want like two 100w heaters.

You must purchase one separately. There are several that work well. Look at "what others buy with this item". This is a great heater and inexpensive to use.

The 3 heater heads are all attached but you can only turn on one at a time if you do not want all 3 heads lit. This is a really greater heater we are very pleased with it.

Not a problem... I'm using mine in a 6 gallon acrylic tank and I'm very happy with it. Keeps the tank at 75 in a 60 degree room through the winter. I would recommend this heater you wont be sorry.

no, there are three heaters in this unit and they each require a dedicated 40 amp breaker.

For a 150 gallon tank. I am assuming that it is fresh water, but either way, I would purchase 2 - 300 watt eheims. If you have returns, I would place one in each. The reason why two is for redundancy if one fails. I have two setup on an Apex system and can keep the temperature constant at +-2 degrees. Also if you have to elevate the temperature of the tank to cure something like ich, having the two heaters will ensure you can take the temperature up.

If all 3 levels are heated by the same furnace one unit should do the trick. Just put the sensor in the zone that receives the least heat. However, if each level is served by its own furnace you will need 3 units.

Robert, we have two twenties on line with our heater, but I can't think of any reason why you couldn't use a 100# tank

I have the 12 gallon and it doesn't have a heater but one can be purchased for either size from Amazon Fluval EDGE 6 Gallon Aquarium - FLUVAL EDGE 25W COMPACT HEATER

Switching the heaters from tank to tank should be easy enough. Making sure there are no sudden temperature changes is the hard part. With two heaters in two identical tanks in the same room this might work, but only if the two heaters have exactly the same setting. This might not be true. Just a degree or two difference is enough to stress a fish (says some web pages). You should check that the two tanks are at the same temp with a really good thermometer. I have just one 2.5 gal tank and change about 10% of the water daily by drawing off a quart (with a turkey baster) then warming a quart jar of new conditioned water by putting the jar in the tank for half an hour or so.

No, this can only be attached to 1 tank. The black phenolic plastic knob with the regulator is the tank aatachment. To hook to 2 tanks, you'd have to get another regulator and required fittings.

No heater. But that wasn't an issue for me, as I live in Texas, and the problem here is keeping the tank cool. :-) LOVE the easy-access port all the way across the front of the top.

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.

It is not a practical tank for adding a heater. Bettas usually do not need heater.

The unit is a stand alone way of heating the water in the tank by additing a metal heating rod separate from existing devices.gas or electric
