So hard to really tell though, so many variables. I do have one available to borrow, I could try it.

They can be sensitive to changes. My foam collapses sometimes when I'm doing something in the tank. I'm assuming from the oils from my skin. Goes back to normal shortly though. It did start to overflow once recently but I pulled the volute/venturi off the pump, gave it a vinegar soak and a scrub with an old toothbrush and it went back to normal again.
