How can I get a white background on product photography

Hello, this is my first post on the forums, but have been reading inputs from others and learned a lot. Thanks!

What I'm trying to achieve is to get a pure white background on my products. I've been trying to change the shutter speed and aperture to get the white background, but every shot I take turns out very warm. (I think it's because I'm using 5400k Fluorescent). Any help would be greatly appreciated!

Camera: Canon 60D - Lens: Canon TS-E 90mm Tilt Shift

Lighting Setup: 2 Fluorescent w/ 6 bulbs on each side of tent, 1 Fluorescent 60W Ring Light on Top of Tent

Camera Settings: 1/60, F9, ISO 200, CWB 18% Grey Card

When I take a picture at F9 aperture, the contrast is perfect on the product, but the background seems a bit red, so I adjust the white balance and shift it 4 steps to the left for more blue. Am I doing this correctly? Now my pictures are not red anymore, but are turning out more blue.

When I raise it to F8 or F7.1, the background turns to white, but my subject is now overexposed and doesn't show the true color. Shooting at ISO 400 with same settings seems to make the subject a bit fuzzy around the edges.

I have included a a picture of the product. Please Help!!!
