Eli5 How the ocean isn’t just fish pee at this point?

Question

So the ocean is full of sea creatures that are constantly drinking the water and peeing it back out a shrine, so over time wouldn’t the entire ocean become less and less H2O and more fish urine (and blood from predation) until it’s just all fish pee? What piece of the puzzle am I missing?

Answer 1

First, pee breaks down after a while and isn’t pee anymore, and second, no matter how many fish there are there’s a hell of a lot more ocean.
