Crack in my sump.....

[Coralgurl]

Noticed I have a crack in my sump. It's located in my ato reservoir, but is only separated by glass inside from the rest of the sump. I can feel it on the outside of the tank, not the inside. The crack is on the backside of the tank and starts on the bottom. The sump is on foam, not sure how this happened, there's nothing there for anything to hit it. It's not leaking so not sure if I should be worried? I'm going to mark it to see if it continues to move.

I can not get this sump out of my stand, without completely emptying the tank so any advice is welcome to prevent a disaster.

Can you take a phone pic? Any crack is serious.

I've marked the end of the crack to see if it's actively moving.

Weird. If the ato reservoir is empty I'd be inclined to bond a pane of glass on the inside of the crack. Definitely monitor it though. Wow, that's a tough call. Maybe Dave or someone has a better solution.

If it moves, glass on the inside won't matter...it's empty right now, manually topping up. Will check in the am, add water and see what happens.

that is what we would call a run!if left it will keep expanding!

best is to cut a smaller piece of glass and silicone over it to preventing for expanding

Do you any bits around dave that I could come grab from you this week?

I agree with a couple suggestions
Short of replacing the back pane, you'll need to drill the crack at it's end to stop it travelling
Then silicone a square of glass over the inside of the hole

Whatever you do, looks like you're pulling your sump out ( again )

The baffles are glass right?
