Another Marine Land Fail

[xabo]

Purchased this 220 less than a year ago and the top brace is already failing.

That's really unfortunate.

What type of lighting are you using? Do your lights provide a spectrum of UV light? Certainly not an authority in this subject but could this be a result of UV degradation of plastic?

400W Metal Halides........................do to the configuration of the basement/ductwork lights are aprox. 9"-10" above the tank. perhaps it's time to think about LEDs.

Great question. I'm guessing it's more likely radiant heat softening the plastic than UV exposure making it brittle.

LED's would certainly help redirect/reduce heat. You could also improve ventillation.

Wonder if using some type of glue/adhesive (JB Weld) will help to prevent additional spreading/breakage?

Mine has a crack like that, but was due to my light fixture nicking it. It happened several years ago and have had no issues with spreading  or anything else.

Do they sell replacement braces? In the mean time, maybe a couple bar clamps will help just in case...

 

I put a piece of foil across my center brace when I had halides, but where yours cracked, it prob wouldn't have helped.

I believe that you can find replacement frames for the top. An old member, Coral Hind, has pictures of a repair that he did in the past on a broken brace. One of his more recent posts shows a picture of it, in fact. However, the break was not in the frame where yours is, but was an more in the crossmember. Search on posts that he's made lately and it may turn up.

That trim looks like it was overheated by the halide. I've had that happen to the same tank twice and then we stopped using the center halide and there were no more issues with cracked trim.

It's not the fault of the tank, but the lighting application itself.

Yes you can buy replacement braces. In fact, I just sold the one I had on Saturday night......the night before I noticed the damage. I've had the brace for about a year and couldn't give it away.......

Isn't that always how it works? You keep something forever (hoarding) and then finally toss it. The next week you need it.

Yeah but...................the Wife doesn't see it that way

Time to upgrade to a 500g with glass bracing
