Heating a 290 gallon tank


I'm in the process of setting up an 8' tank in our office lobby. Because of where it is located, a sump was out of the question so we went with canisters. The lobby temperature stays around 74 degrees +/- 1 and we're shooting for a target temp of 79 so I'm not trying to make up a huge difference. As we're trying to limit the amount of unsightly things inside the tank, an inline solution would be preferable, but the only products I've found don't seem to have adequate heating capacity. I'm looking for suggestions.

Hydor is the only inline heater company I know of. All of their heaters are 5/8" diameter, and their biggest is 300 watt(I think). My guess is two of these should do the trick. Or you could Google some diy inline heater ideas.

I use two hydor's on my 125g. I break the return into two separate lines.

You probably want to break the return into 3-4 lines if possible. This way if one goes bad you have back-ups that can handle the volume. If you only have two and one goes you might be in trouble and you don't want that in an office setting.

Not sure on your budget but you could do a heat exchanger inline using a hot water recirculator. This would be more expensive but you could then only have one return line.

You can see the two lines I have in this picture...

I imagine 600w of Hydor inlines would work fine? Your temperature differential is not that much.

I agree with splitting the return, maybe not for the same reasons as stated above though. My hydor has been going strong for over a year now with zero issues. On a tank that size, I would run at least two canisters, probably two fluval fx5's. One hydor on one side of each filters split and reduced return. So, four returns and two intakes. I run a hydor on my fx5, so if you go with this method, feel free to ask me questions.

Can you install the inline heater to the inlet line? I figured the water is flowing downward so it's easier for the pump and you don't have to sacrifice the water return rate.

I would stick to the outlet so the inside of the heater doesn't get "gunked" up with stuff.

That is true! Does the inline heater really slow down the return rate?

I use a hydor inline on my 100gallon and it does just fine hooked to my FX5. My house is at about 70 degrees plus or minus a degree or two, and its rock solid at 78

Not one little bit.

How did you work you hydor into the 1" plumbing. I mean, I know how I did mine, was just wondering what methods other people might use.

Ok so I took a threaded 1" reducer to a 5/8" barb.. then i used silicone on the threaded end and a hose clamp on the barbed end I used clear tubing from the barb to the heater and from the heater to the barb then back to fluval tubing.....I didnt lose that much flow and i have no by pass. and 100gallon tank with water strait from the tap took me about 6 hours to bring 65 degree water to 78 degrees. I think on my journal there is a pic of my inline setup

Simple = better in most cases right?lol. I was going to go that rout, but thought that the added back pressure might damage the fx5 pump. I split the one inch into two 5/8" outputs. Diy spray bar on one side, heater on the other, open end.
