zennzzo;4166549; said:Capacity is the name of the game for sure...If you are going to run a sump then put all the heaters in the same place either the tank or the sump not in each...there is a slight heat loss from sump to tank like 2-3 degrees F.
Also if you are going to run multiple heaters, I would use an external heater controller.
This way you won't have one running and one idle when you get close to the desired temp...How they work is just like the thermostat on a single heater.
There is a thermo-probe to sense the tank temp, and then based on the controller setting it will power up to 1000 watts of heaters until the desired temp is reached, then it will power off the heaters, when the temp is reached...
The Blue Line controller I have, will run up to 1000watts of heaters. You just turn the thermostat on the individual heaters all the way up and connect them to the controller.
Drop the thermo-probe in the tank and set the desired tank temp on the controller...When the tank temp drops to 1 degree below the set temp it sends power to all the heaters, when the set temp is reached, it shuts off the power to the heaters...This way they all share the load equally, and there is no problem trying to calibrate the individual thermostats to come on and shut off all at once... You'd be surprised how much less the heaters are on especially when you approach the desired set temp...About the price of a premium heater and you'll always know what the tank temp is and what the set temp is as well as the current status of the power draw.
(if it is running or not)
With a controller I was able to run my 225g acrylic at 82-86F in a room that was 68-70f with just 2 x 250 watt stealths in the bottom of my 90 gallon sump that was turning over at 2600GPH....![]()
Nice, good info. I guess I can Just use the 2 I have now on my other tanks. I guess I'm just a sucker for Hagen products and the whole Fluval line. I've had nothing but good luck and long reliable use out of all their products. The FX5, for a canister filter, is quite simply amazing. Ive got a 50% water change, mix salt, clean both the 405, and FX5 and scrub the tank and deco down to about 45min-an Hour. Pretty fast for how much crap those filters pull lol.
BTW, is Weekly 50% changes AND weekly filter cleanings a little excessive? HAHA, Gotta keep their stuff clean and my fish healthy
