curcuit keeps getting blown

[thrawn150RT]

I had a new 90 gal reef ready tank setup when I had my office built out. It has been running great for 2 1/2 months the only thing on my electrical circuit besides the fish tank is one can light. Over the last 24 hours my breaker for the tank has been thrown twice. I thought it might be my CF lights causing it so I shut them down, but it just did it again. I am wondering if it cold be my return pumb since it is also pulsating sounds like waves, but if you look at the retrun on the tank you see the level going up and down. Any thoughts?

Sounds like a short somewhere

Put a GFI on the circut if you have not, and yes it sounds like a short somewhere. Check your wiring, surge protectors, and if you have and DYI stuff lool at you connections.

after testing various combination it looks like the issue is the heater. It is the old peice in my tank. Water heater would folk req for a 90 with a 20 sump.

Do you have a GFCI on the tank? If not I'd add one, I don't like putting my hands in water with cords running nearby without one. I also have wet socks because I spill alot :)

Awww come on folks.....110 kind of tingles and after enough shocks it actually tickles!!! :hmm6: :hmm3:

I do have a gfci on my power that the tank uses. That was a must when I had the office built out.

Is the GFCI outlet tripping or the circuit breaker at the distribution box?
Or is it a GFCI breaker?
Do you have a surge supressor power strip plugged in?

There are a few things that tend to trip GFCI's. Lot's of people have had the same problem as did I. I stopped using GFCI's because of this. I wish I could use one but checking the tank and finding the GFCI tripped for who knows how long is not fun. I finally had to get rid of mine and have not had any problems with power since. They are not for everyone.

Have you considered a faulty breaker?

Though replacing your heater sounds like it will fix it from what you've found. For a 90, I'd do 2 250W heaters, preferably on controllers.

If you don't use a GFCI breaker, you should at least use protected power strips (fused/breakered)

Also make sure you're not drawing too much power (amps) when the system is all running. The heater, pumps, lights, skimmer, etc. might be drawing too much current for the breaker especially if it's an older 15 amp breaker. When the heater kicks on, that could be the final straw that puts you over.

This is even more likely if something other than the tank is on the same circuit (it sounds like you already did check this though).
