It's not a very big sump. It's the number 2 model All Glass sump. There are water lines on it, I never go higher than the line.
Actually it might me less than 5, I've never measured it correctly, might be 3 or 4 left, when it's at it's fullest. I don't even know the full size of the sump, doesn't say any where, I think it's 20, might be 15 though.
