sumps and water changes

[Dan F]

Hi forgot to say this is all wet.
I have got a small pond pump lying around that I could use.

Since your media is all wet, I think you're fine. You could always throw an air-stone in your sump if you are at all worried.

I think I will put in the air pump just for my piece of mind.
So with that you think I will be fine for 2-3 hours?
I have got a 40 gallon tank where I heat the water and I can empty that into the tank then I would have to wait for the next lot to heat up so I think 3 hours really.
