I am setting up my new system and want to make sure I am not pulling too many amps for the breaker. Can someone tell me how to convert watts to amps??
Thanks!!

Amps x Voltage = Watts
So Watts/Voltage = Amps

so assuming you are running on a 110. Then you can divide
Watts/110 = Amps

Cool thanks!!! I am running on a stardard 110.....and I am also running 20 amp circuits so I will just have to calculate everything and most likely use a few different circuits to run my equipment.

+1

Always good advice not to run close to the "posted limit". Better to upgrade w/another circuit than to overload an existing circuit.

Just to add on what brother IBEW41 stated, it is also a good idea to make sure that the breaker (15 or 20 amp) has the proper size wire on it. #14AWG for a 15 amp breaker or #12AWG for the 20 amp breaker.
I'm sure IBEW41 can tell you how many times we have seen wrong size wire on the wrong breakers, especially in residential work.

ALSO,
Just to point out you should also find out everything that is on that circuit. Sometimes you may have other things loading it and you may push the circuit to the limit.
Always better to have a dedicated breaker on your aquarium, but usually not always achievable.
Also, I would put in a GFCI outlet on that circuit.

I would use a seperate branch circuit with a GFCI breaker used for spas and pools. The cost is not much more GFCI oultet.
GFCI (Ground Fault Circuit Interupter) also protects all circuits after (in that branch circuit).
GFI ( Ground Fault Interupter) protect only that outlet
More then one breaker dont forget about LOAD BALANCING.
