my 160 does not have a top brace tank was made Feb. 17 1992.
that said my 55 does. It broke two weeks ago. I didn't think anything of it until last Wed. when I was doing a water change and notice the brace is a 1/4 inch short from reaching the side. in other words the tank has bowed out in the middle.
So I bought the stuff to fix it.
there are a few ways to fix the brace.
lexan/acrylic brace over the broke one and drilled screwed and glued. or a piece of angle iron/aluminum cut to the outside of the tank with and placed on it to hold it together (ugly)
I'm going with the 1st method.
drain tank about 1/2 way, use bar clamps to bring tank back to spec., cut lexan brace to fit.
cut new brace to fit pre drill your holes, glue new brace, glue it, while glue isstill wet, bolt with stainless hardware, wait for glue to dry remove bar clamps. Fill tank.
My only other option is for me to swap tanks. I have a neww 55 with the snake in it. swap tanks and be done the snake has no pressure in it since there is no water volume. it's easier to just fix the brace then spend 1/2 a day swapping tanks.
