aquarium heater

I can't seem to find an adequate heater for an aquarium of 100 gallons. Any suggestions?

When I upgraded from my 55 to the 120-ish, I got two of cobalts higher end units. I'll look into which ones I exactly got when I get home from work.

Hello, maybe you could get a couple of sm heaters(3×200w or 2×300w) this way you could distribute heat better around tank. I use 3×150 for 55gal. 1back center & 2front corners. Hope this helps!

You'll probably have to get 2-3 heaters for a cumulative effect. The upside is that the failure of one won't be immediately disastrous to your tank.

Two 250 watt heaters will suffice

Sorry it took so long to reply, but these are the heaters I'm a fan of.

I also know that bulk reef supply did a video comparing heaters that might be of assistance for you to look into as well. I know it helped me make my decision.

I wanted to put the heater(s) in the sump. Do you think it would be better in the tank? I really want to keep the water temperature consistent.

Keeping heaters in sumps is very common and won't cause any variation in temp.

Hello jb...

I've used Aqueon for quite a few years. I use 300W heaters in my larger tanks. The important thing is to use equipment that will distribute the heat evenly. I've found dual sponge filters do a good job of moving the water so the heat is distributed evenly around the tank.

I would also look into a heater controller. These devices will monitor the temperature and will shut off the heater(s) in the event they malfunction (for instance, get “stuck” in the ON position).

This. Controllers really are worth the peace of mind, though you should have a look at this video for a possible, but easily fixable, problem:
