I want to install a small submerged filter in my tank, the Duetto DJ50. Even though it is supposed to be safe to run under water, I want to be extra careful and encase the power cord in a vinyl/platic tube of some sort and seal it so that the cord does not get exposed to the water. Is this something that someone has done before and if that's the case how did you do it ?

Well normally they come that way. Besides it's not the cord you really have to worry about. It's where the cord enters the filter and the motor.

I've had a DJ50 running in a fry tank for a while now and it works just fine as is.

I think what is bothering you is the notion that putting electrical equimpent under water just doesn't seem right!

You ought to look into whether the outlet you will be connecting to is protected by a Ground Fault Interrupter. If the electrical equipment should fail, and you stick your hand in the water, the circut breaker in the outlet will trip before you get electrocuted.

If any outlet on the circut is replaced with a GFI outlet (about $15 at a hardware store IIRC) then all outlets on the circut are protected. Bathrooms and kitchens and other wet locations are typically procected according to building code. But you can't assume that the protected outlet in your bathroom is going to be the same circut as your bedroom. Could be that several wet locations (kitchen, bath, garage) are on the protected circut and no bedrooms at all. And you don't want to install a GFI on a circut that is already protected, it's just annoying, "Which one popped, the one in the garage or in the hall bath?"

If you find a funny outlet with two colored switches -- that's the GFI. Push in the button that is out and see what turns off, maybe the tank is already protected. Be sure to push the other button to reset.

I think that you can get mltiplug outlets that are GFI protected, but I'm not sure. I really ought to find out since I just realized that my bath GFI does not protect my tank....

anonapersona, it's very worthwhile that you mention the extra safety that gfci's bring to the table. however, just to clarify a few things as i understand them:

1) gfci's can be wired to protect ONLY themselves, or, themselves PLUS other circuits. so we can't always assume that all outlets that are on the same circuit are protected.

2) a gfci can only protect other switches, receptacles etc that lie "further along" in a circuit. in other words, it can't protect receptacles that exist between it and the main panel.

3) as anonapersona pointed out, we wouldn't want 8 different outlets protected by the same gfci. tiny fluctuations in current flow can lead to "phantom tripping"; if you were on vacation you obviously wouldn't want your fridge to be on this circuit

4) gfci's should be tested at least once per month. yeah, like i do that...

there is some info on apd regarding gfci's. i realize some of this may appear to be off topic, but safety is something we all may need a refresher on once in a while. some of you may find these links useful:

anonapersona, thanks again for bringing this up.

I had no idea that I'd been carrying around that mistaken notion about the entire circiut being protected. Thanks for the correction.
