Stainless filter screens

You could try an inline y strainer. I use one after my pump on my hydropanic setup so the spray nozzles do not get clogged. It is made out of PVC and the strainer is all plastic with what I think is a nylon mesh. It works great. I have to clean it every couple of days but it really does a good job of mechanically cleaning sediment out of my system. I will try to get a picture of it you want but you should be able to get one at any hydroponic store.

All stainless steel can corrode, it resists corrosion because of the chromium alloying agent which reacts with oxygen to form a film of chromium oxide which protects the internal steel. However oxygen is required, you'll notice many stainless steel parts will show signs of corrosion over time in areas of contact with other surfaces. For example your stainless steel coral shears corrode around the pin first and spread outward. Also your kitchen knifes corrode in the dishwasher if you put them on the rack (the rack stays in contact with the knife surface preventing oxygen to react with the chromium in those areas).

So in short no stainless steel should be used long term in aquariums, especially saltwater, any contact points on the metal will eventually corrode like any other steel.

Thanks for the explanation. I will drop that idea.

I got mine for about $15 bucks at quick grow on edmonton trail if you are in calgary. They have a couple sizes to fit your piping as well.

The Y strainer sounds ideal, but the ones I saw online in the U.S. were expensive.

You might also try inline filters for bilge pumps on boats, they are cheap and have clear plastic covers. you will still might have to swap out the stainless screen for plastic. Maybe CdnTire?

Here's one for an example

Maybe a filter bag on your overflow line in the sump would help as well.
