Default newb question: keeping water at correct temps

just starting out here with a letter raft / bubbleponics type of system. Finally finished all the hardware, but filled the res with a few gallons of water and it's been sitting unaltered for soon approaching 24 hours. I was really testing for leakage but what I found is that the temperature of the water is way too cold. I need to get a thermometer but it's way colder then when I filled it. This from sitting in a room that is fairly small, fairly tight with a duct register in the room. Our thermostat is I believe set to 63F.

The lights were not over the setup, but I'm running FS cfl's (= 500w / real 110w) still doubt that would heat the water. So what is a good way to heat the water. I think aquarium heaters might work though it's Roughmate tote so I have no idea about the safety.

Any ideas ?

you cant get any thing better then a fish tank heater. 300watt heaters work great.
They have inline pool heaters, but i think that is way overkill for you.

Yes the fish tank heaters will be perfect depending on how many gallons you are heating. They usually tell you what size fish tank heater they are for (5-15 gallons etc.) You can probably even use it for more gallons than that, as long as it's not way over like 50 gallons for a 15 gallon heater. Also most fish tank heaters that have pre-set thermostats are set at 78 degrees, that's too high. You want the adjustable thermostat models. The nutrient solution temp should be between 68 and 72 degrees, can be a little lower but should be not higher. You can get fish tank thermometers for around $2. Although I wouldn't recommend the stick on kind they are hard to read and I don't think they remain accurate that long.

Thank you people. I'll make a trip over to the aquarium shop and see what I come up with.

Okay even better. But just to check again I need not worry about it melting the plastic on the tote . I gather it would sit a bit off from the surface just not sure how far.

PS I called the aquarium store near my house, their smallest titanium is 200W
That's probably overkill.
