heater in sump

[tang daddy]

try adding an additional heater!
I use to use 1 larger heater for my reef until a freind suggested for me to use 2 smaller, I scratched my head and asked why add 2 when I can use 1?
He replied if 1 small heater stuck on your reef wouldn't cook, the likely hood of 2 failing is very unlikely and if it did I would have to go buy a lottery ticket. btw total water about 180g and am using 2 200w

There's definite merit in two small over one large specially if relying on the heaters own thermostat rather than a external controller.

Didn't cook a tank but probably came close once on my old 75g when the single large heater stuck on.

Thanks very much for the advice
