sump has sprung a leak

[jam]

ok so 1 of the baffles on my sump has sprung a leak at the bottom,so now it doesnt really work properly,the water drains out thru the hole/crack in the silicone, sand has gotten into where the return pump is housed,is there any way to fix this without tearing the whole thing apart, its a standard sump i guess, if there is such a thing(baffle, upside down baffle, baffle, sump/fuge area, baffle, return pump-i dont know if this would help:

You can try a small bit of reef epoch. Won't be pretty but will work while it is still filled.

+1 fast

At least it's not leaking OUTSIDE of the tank :D

yeah, hopefully i can avoid that, i ordered some reef epoxy, hopefully it will work, meanwhile, im just gonna take the sump offline, the big blackout here kind of got me going in that direction anyway, thanks for the help..

If it is out just get some aquarium silicone and attach a piece of airline to it that is long enough to get to the leak, and use that.

will that cure underwater?
