I'm not sure how RSR tanks are made, but just remember old silicone doesn't bond to new silicone, there's probably going to be two little sections where the new glass siliconed to the old glass where old and new silicone are in contact.
This is also the long pane of glass isn't it? I'm not sure a repair would be worth wild.
I’ve read some threads in the forums where people just replace the one piece of glass, new silicone and done! Images showed the finished work and no leaks.
Is my understanding that all the glass pieces have to be taken apart, cleaned of all the silicone and put it back together.
My first attempt at re-doing a glass frag tank ended in cracking one glass piece.
Have a RSR250 that I picked up in Discovery Bay with the back glass already removed. Has been on the work bench for a while and I’m gonna try this time just placing the new piece of glass then test it for leaks, but for a guy who’s dry in the hobby, I don’t mind the time it’ll take to be accomplished.
RSR are made the same way but they feature a black plastic piece bonded on top of the silicone.
