tobyfishkeeper Posted July 5, 2023 Share Posted July 5, 2023 I started a pleco breeding tank a while ago and now i need more caves so I am wondering if anybody has knowledge about if you can use a stainless steel pipe like the pictures. I am very thankful and this is my first time on this forum, I am from Sweden but found it by searching on some pleco cave stuff. Awesome threads!

DaveO Posted July 5, 2023 Share Posted July 5, 2023 You should have no problems using stainless steel in your aquariums. The main added element to make iron stainless is chromium. It is not toxic like copper can be. I have stainless machine screws attaching a light under hood in one of my tanks, that remain wet all the time. After two years there have been no ill effects. I think you are good. Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted July 5, 2023 Share Posted July 5, 2023 My only thing to add is to ensure there are no sharp edges so the Pleco’s don’t get wrecked going in and out of those caves. Best of luck! Link to comment Share on other sites More sharing options...

Yeah good tip! I heard plecos like the roof of their cave a little rough, idk how to do that though. Thanks! Link to comment Share on other sites More sharing options...
lefty o Posted July 5, 2023 Share Posted July 5, 2023 depends on the series of stainless. 300 series wont rust, 400 will. 1 Link to comment Share on other sites More sharing options...
tobyfishkeeper Posted July 6, 2023 Author Share Posted July 6, 2023 Okay, how can I see or test this? Maybe there's a marking somewhere? Thanks Link to comment Share on other sites More sharing options...

nabokovfan87 Posted July 6, 2023 Share Posted July 6, 2023 Agreed @lefty o there's a lot of different grades, types, and shapes of metal. All of which vary batch to batch, let alone material type. One of the big issues is always going to be what is the specific spec that you're using and is that best server for underwater use. There may be an avenue of research given for something like engineering guides. Usually there is a spec, SAE or ANSI or something on the material itself that you can use to verify the material. If there isn't a stamped spec, then you're pretty much just guessing at what you're working with. Older stock may have the markings removed too. My analogy initially when seeing the thread title would've been cooking pans and how stainless vs. carbon steel vs. aluminum vs. copper pans all leech different things. There is some research and studies into this topic and that might be helpful for you. Link to comment Share on other sites More sharing options...
