How long to immerse in saltwater to test Stainless Steel

Postby dudedudedude » Fri Mar 24, 2017 10:57 am

I bought one of these for a DIY flow project but it doesn't mention what type of stainless steel is used.

How long should I immerse this in slat water to make sure it is reef safe?

Any input would be much appreciated

Even poor quality stainless steel will take a long time to rust. Just a guess but maybe a month or two before seeing serious signs of rust. Could be much sooner.

GFO is used to remove phosphates and its made of rust. I've also seen lots of stainless steel hose clamps rust in sumps and it never caused any problems. I don't see any problem with a little rust.

I'm more concerned about what type of lubricant is used inside of pumps. Any type of petrol based lubricant is going to cause noticeable losses when compared to rust.

I agree with Victor. It will eventually rust, but the rust is unlikely to hurt anything. I'd be more concerned about any lubricant and if there are any copper or brass pieces in there, which will cause major issues.

What is the purpose of adding this?
