Thanks for your input. Much appreciated. Working on my first sump. I bought it on Craigslist. But I have to redo the plumbing.
Its a 150 gallon with 5 chambers

Im thinking on putting mechanical foam and sponges in 1 and 2 then pondmatrix and bioballs in 3 then pothos growing in 5. What should i put in the other chamber? What would u change?

I've seen plenty of rusty hose clamps and what in tanks. Should not be an issue.

I've used stainless steel hardware for years without issue. These are the types of applications it was meant for.

I'm another guy with lots of worm gear clamps either submersed or always getting splashed.

As a former parts guy and salesman I can tell you to spend the coin on "marine grade" hose clamps designed for boating use.

9/10 clamps at the parts store or home improvement store have galvanized screws or brass screws. Few manufacturers use stainless steel screws.

Ive used stainless in aquariums since ive started with fish keeping. Most commonly available stainless is 304 stainless, its basically corrosion resistant not rust proof. It just basically rusts reaaaally reallly slow. It leaches pollutants at a very slow rate nothing to be concerned about, at least I'm not.

If you have the pick of the litter 316 stainless, particularly low carbon 316 is a choice metal. Surgical grade. I work in a food plant now, everything is low carbon 316, we spray the equipment daily with caustic chlorinated cleaners, phosphoric acid, etc. Stuff is 35-40 years old. No signs of corrosion. Aside from the occasional scratch or gouge the steel looks brand new
