Litefoot is absolutely correct, as the only filter, a sump is a terrible idea for a turtle tank, for the reasons he explained.
However, it's a great addition. I have a large canister filter and a 55 gallon refugium--sump with plants in it. It gives me a place to grow plants for the turtle, that Tobie can't eat until I decide the plant is ready. The floating duckweed is great at sucking up nitrates and making those canister filter changes further apart. Water level in the main tank is always the same.
And, the time my canister filter died, I could wait days to order online because of the biocapaciry of my sump.
I would not want it as my only filter.
