Diatoms

Maybe this is an absurd question but Ill take the risk. Once a fish consumes live diatoms will they be dead by the time it exits the fishes digestive system?

Someone has posed to me that a saltwater fish tank only can have zero diatoms if not introduced in live sand and rock. It you methylene blue the newly acquired fish killing free floating diatoms this would be one way to eradicate them before introducing them into the tank, however a fish intestine is really short.

Again were talking about a fish only system cycled with ammonia & bacteria. Is it possible to totally evade diatoms?

Too late but, if you cycle your tank with the lights off you can avoid algae issues. At this point I'd recommend reproducing snails and a bristle tooth tang, like a Tomini, which eats detritus and sand bed (and rock) algae.
