Have my tank in it's beginning steps, but I just randomly thought of this:

Will a moderate to heavily stocked (fish) tank provide enough nutrients (along w/ a decent substrate) to avoid the need for ferts (low-ish light low-tech tank). Thanks.

It depends. If it is a low light, low tech tank without CO2, it might work. Problem is that those sort of tanks are often setup so you don't have to change water. That doesn't go along well with overstocking.

If it is low tech (no big nutrient needs) and regular water changes are done, it might work.

Keep in mind that fish tend to grow. What today is medium level, tomorrow could be way overstocked.

This is no-go for normal planted tanks.

Thanks for the info. One more thing, what exactly would you hope to be removing w/ the water changes that would need to be removed in an overstocked tank?

And are there any non-chain fish stores up there? I haven't looked since I've gotten in the hobby but I'm from Salinas.

Water changes remove build-up of dissolved organic components. Unfortunately, our fishies don't poop just nitrates and phosphates, so over time water degrades. While they can handle swimming in their own pee for a while, it is not a good way to keep them. Many years ago ppl swore by "aged water" and found that water changes would kill their fish. That was with once-a-year or so water changes, drastic changes... With weekly changes there are no problems.

(Just as a little disclaimer - I think overstocking tanks is a REALLY bad idea, leading to many unnecessary problems).

Salinas is pretty sad LFS wise, besides the usual Petsmart there is Petfun with its ich-ridden lifestock, and another LFS down on S. Main that just scares me. There is a brand new store in Old Town, little hole in the wall, cartering to marine hobbyists. Nothing exciting here in the area, you'd have to go up to San Jose to find some decent stores.
