If you have a 10 gallon and replace 10 gallons per day, isnt it more like a 1000 gallons water capacity chemistry wise? Or a million gallons?

Imagine a slow drain of new saltwater contimously replacing this tanks water with clean water all day. 10 gallons or 5 gallons a day.

I kind of want to set this up just to see how it goes.

There is setups like this, just look for Automatic water changes.
I'm not sure about your math bit there a little calculator somewhere that tells you how much water you're actually changing when you do a wc, and how much original water is left after a series of waterchanges.

So to be clear you want yo continually drain and add water to your tank... i guess in theory itll work but it wont give your tank time to stabilize (cycle) water chemistry... maybe 1 gallon every 2 days or something like that may be more suitable. Also think about the amount of money you will be spending on salt to make water.

I have heard about a tank like this. Search auto water change

Yes i see, but salt for a 10 gallon is cheap. Think of the cost of test kits, and additives. With salt you dont need it. Instant ocean 160 gallon mic at 5 gallons a day is a month or so of water changes for a 10 gallon.

A number of artificial salt mixes contain ammonia......it's just in there. You're fine doing lower volumes of water changes, but I'm concerned with changes over 50% (to pick a number). I certainly would not consider repeated 100% water changes, with the concern with excess ammonia.
