I bought a 500 Watt Titanium heater for the 100 gal RubberMaid Ag fish tank, thinking that was large enough since they are typically rated at 100-160 gallons. At the maximum setting I am getting only about 72F out of it. Since I need to raise the temperature for the tilapia closer to 80+F, I am looking for 800W or 1000W unit, which will be the main heater. The current 500 W will be the back up.
Anyone have any experience with this line of heaters?
JBJ 800W True Temp Titanium Heating System.
Seems a bit pricey, but I don't mind paying for quality if it'll do the job and last. Any other possible recommendations?
Considering couple other options: (1) build Randy Mossman's DIY heater using 2000 W 120V electric hot water heating element; (2) build 4x8 solar hot water heater using CPVC [http://youtu.be/WP8H5IOTwYU]. The system is on the south side of the basement wall and it would be simple to pump this. There's already a hole there where the heat pump pipes are run. Would need a second pump to circulate water up to a head of around 18 feet.
A third option might be evacuated tubes set up something like this: http://www.electric-bike-kit.com/solar-tubes.aspx. System uses 2 inch PVC and could be modularized depending on the size of my tank. Would make an interesting experiment, for sure. Any thoughts, anyone?
Yeah, hehe...use a different breed of fish :)
But we like Tilapia! ;-) Anyway, I've already invested money in buying an Eaton thermostat with temp probe, 2000 W electric hot water tank coil and Randy Mossman's adapter.
I HAVE 3 OF THEM YES. PRICEY BUT GOOD .WILL DO THE JOB
Follow-up: Over the weekend, I make the set up semi-permanent. Check out the photo in the gallery. I put the Eaton thermstat inside a blue shallow double receptacle box and cover. 10 ga. wire to the heater are inside plastic conduit. I found the correct setting to maintain the water at a 74-78F temperature range, which is what I want for both the tilapia and the gold fish. Very pleased -- so far -- with the results.

Hey... I am also charging an electric hybrid. Goal is to eventually go solar for the hot water.
Rule of thumb on pond heating: 1 Watt per Gallon = 10 degree rise in water temperature. Example 1500 watt (1.5 kw) to heat a 1000 gallon pond by 15 degrees over a 24 hour period.
