I have sand in my planted tank and the stems are all doing fine. The crypts, enh, not so much.
In a 75gal, you may need to get a T5-HO to get enough light down to the bottom.
Ah, if this is a tank for goldies, then you'll want to stick with swordplants; goldies might eat anything else except anubias and crinum. Make the sand bed at least 3 inches deep and use a stick fertilizer or an iron supplement. Still might want the T5-HO; swords will do okay in low light but better in higher.
