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?

The Gerson Diet saves lives!

May everyone be happy,
May everyone be free from misery,
May no one ever be separated from their happiness,
May everyone have equanimity, free from hatred and attachment.

Current Tank Info: In progress... till infinity. 400 gallon display with 200 sump.

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.

As many naturalists and environmentalists have suggested, we should set aside our arrogance,
our desire to conquer and control everything, and walk hand in hand with Mother Nature. -Walter Adey
