One of the Reasons I Don't have a Sump

Poor guy :eek:

Just a freak accident. And I notice that there are muliple holes in that tank.
Certainly not a case for not drilling a tank. I can show you more threads on devastation caused by heaters, but nobody chooses to not use heaters.

WOW I was just looking to see if the guy lives in Stony Plain sounds familiar huh Ed? :lol:

Holy smokes :sad:
I had a power outage where I live this morning. I could not believe how fast my tank started to drain. I'm lucky though, mine is drilled in the back pain so it stopped emptying 2 inches from the top !
Scary stuff!
You don't hear about it too often though!

You don't have a hole to break the syphon drilled in your return line..? :confused:

Brad,

I, too, have read about horror stories regarding faulty heaters and, yes, I still use heaters but feel pretty sure I am safe because my tanks are grounded.

Anyway, can you tell me if a heater, or anything else electrical, in one of my tanks malfunctions, what kind of damage I would incur with a grounded tank? I know if the malfunction happened during the night, my tank would completely shut down. With lack of O2 and water movement, I would assume some/lots of stuff would die. But if it happened during a time I was home and the down time would be only a couple of hours, what would the initial electric shock, before the tank shut down, do to the inhabitants of my tank? In your opinion, that is.

considering most of the heaters on the market fail ON, you would boil the fish, the corals, the rock, ect and you would lose everything like I did. :evil:

as for the thread, bad choice of where to drill it coupled with an unsupported bottom. all that don't support a tank with trim is bunk if you use a foam that will take out the irregularities it only adds to the strength and resistance to cracking. but bulkheads drilled along the middle are just bad, you can see the progression in the pic, the two closest to you started it and the shift caused the 3rd to be included. so you have an unsupported bottom, with rock pilled over the weakest point and nothing to resist the localized downward force..

at any rate a lot more heaters, overflows, ect have caused floods than tanks breaking because of being drilled. :exclaim:

Wow, that would be terrible to come home to. I would never have used a tank with holes drilled that far from the edges myself....not in the bottom. My current tank has the 2 corner overflows, but even then there is another piece of glass siliconed into the overflow and the hole is drilled through both, providing more support.

Still scary....

Makes me think about building a sump. But then again what are the chances of that happening.

With a typical corner drilled tank, slim to none. More on the none side actually...
