At least 1 1/2 times deeper than his shell length, so minimum of 5 inches, preferable more. They instinctively know how to swim, so ideally as deep as you can make it without making it easy for him to escape or be too close to the basking lamp. My 4.5 inch turtle has about 15 inches of depth and he loves it. You should also have him in a minimum 30 gallon tank at this size, preferably more as he will continue to grow.
