Hi Maximus,

The screen is 316 stainless steel, which is considered "marine grade" due to its near corrosion resistance. Many common pump parts are also made from this material. While it's impossible to say that it could never corrode, we haven't had any experience or complaints about it causing any trouble in a reef tank. I use several of them on my personal system, as does Dan.
