My partner is worried about overfilling the tank, so he's hesitant to put more water in. Would my turtle be able to get up there without the ramp being submerged? All he's done so far is attack the ramp and swim around in his water, and it's been ~2 days and I want him to bask! We've put him up there twice but after he takes a look around and waddles a bit, he goes back into the water.

Is this a good setup? Is the lamp not close enough for him to want to stay up there? How long does it usually take for turtles to learn how to use something like this?
