304 was less expensive and there isn't any extra benefit to using 316.

I read once that 316 is better in a marine environment. Nutrient solutions are a milder form of the same kind of load. But I do not know with any certainty.

Yeah as far I understand it would be better for marine use but the nutrient water would never hit those kind of salt levels. I probably could have used a lower grade material and it would still be fine.

Chloride ion is something special in terms of corrosive power, so I think you have a point. However hydrochloride acid is my “go-to” for removing mineral scale. How would you descale?
I got a plastic box from Lowe’s for $14 that does the same, not as cool though. Bigger the better for Rez size.

I did some work at a micro brewery about 16 years ago....welds have to be first clean and sanitary so nothing can grab hold and grow......then it has to stand up to the beer and cleaning after! Always wanted to incorporate tri-clamps and SS into my grow set up but it doesn't make sense.

Any salt build up can be removed with a scrubber that you would use for pots and pans. I soaked the blue feeding tubes in a vinegar water mix which loosened everything up enough to come off pretty easy. Everything can be reused which is another great thing about these units. Less garbage in the landfill and money saved in the long run.

Hope this helps spark some interest https://www.gvc.net/c/5196/tri-clamp....I like the idea of the coolant lines for feeders but would use plain tubing so it's....1 less expensive and 2 less likely to harbor crap. I understand the funneled tank but it needs more volume......Better SS and smooth welds so no crap can take hold.......

I have used that piping in projects at work. Really not needed for what I'm doing. Those feeding tubes were $1.50 each and hold in place a lot better than the regular tubing. Volume is dependant on how often you want to refill the tank. I could easily alter the design to hold more water if I wanted or have the system automatically fill from a larger reservoir when the level gets too low. For how often I clean the unit (once per month) not harmful germs or bacteria live for very long.
Here's a pic of the larger system in use no issues as far as plant health goes:
