Crack in my sump.....
 

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.

The baffles are glass right?

They are.

I would drain your ato and cut that piece out and put in a new one....then you would know its good and not break and dump water all over your floor

The ato is just separated from the sump by an internal baffle. The back glass is one solid piece and I wouldn't be able to cut it out.

There's a pic of the sump on page 3 of my 180 gl build thread, but attached a pic I drew when setting up.
