    hi guys, I was wondering if would be safe to use stainless steel for a marine tank, I have this idea, but want to make sure it will work first, and that it would be safe? any ideas and opinions are welcome. I was thinking of using 6mm 340grade stainless steel.

    yep im never one to crush an idea, but stainless steel is no match for the corrosive powers of seawater.. it will just take longer to rust than coated mild steel..

    glass, acrylic and concrete(coated ofcourse) are suitable materials for a structuarally sound marine tank.

    give us some more info on your proposed idea.. curious..

    Besides, there are some real crappy grades of stainless steel out there which you dont know of till they start rusting and you dont want that near your tank

    ah damn, there goes the idea down the drain.... I just got the idea this morning looking at a decanter tank, at a chemical plant. liked the idea of the thick round side glasses held to the tank with m20 bolts, kinda liked the whole industrial tank idea. but as you all stated it won't work....damn. thanks a lot guys, as always you're help is much appreciated.

    Build a standard tank and dress it up with steel and bolts to create the effect

    we did this at our local aquarium, the theme was a Submarine, so we used steel with bolts around the edges to give it that industrial/submarine look.. works pretty well

    only one problem the budget wouldent allow for stainless so they went mild steel.. and it looks very realistic as there is no Rust imitation paint but real rust.. you cant win them all i suppose... i would have personally gone with a mock fiberglass prop glued in place..

    use your imagination, there is more than one eway to achieve a trouble free tank with the look you are wanting to acomplish...

    We use stainless steel on the Yacht, there is one stainless steel screw at the bottem at the prop in the water and it needs replacement once a year. else it becomes so rusted we cant remove it.

    stainless steel doesnt rust as in rust away but rust however does grow on it. My cousin biulds ship impellers and anchors and i have asked him about using stainless steel and he said most impellers and anchors are made from stainless and never rust away but rust will bond to any metal.
