The computer fishtank

[groom03]

First off i do physics and i'm not so good at Biology.

i want to build and run a computer underwater, in order to do this i need to use de-ionised water and i thought to make it more fun i could put some fish in there as well but i've read that fish cant survive in de-ionised water so is there some way i can make the environment more liveable for the fish?

make your systems rust proof, you need oxygen in water plus the fish themselves will pee/excrete some ammonia+salts.

I dont quite folow, do you mena that fish can survive in deionised hater or that they'd cause problems for the computer?

I mean I think they'll survive, but your water will get contaminated by organic byproducts as the fish poop/pee and thus your water is never really going to be deionized because you'll still get some salts in it.
