Iron from rocks, danger to RCS?

So I have been working with RCS for a while, and have around 70 individuals, from an original population of 5. I have them set up in a 20 gallon (talk about low bioload), and to make things more interesting, I was hoping to do some hardscaping. I recently went to Sedona, Arizona and picked up several pieces of red rock, which looks absolutely fantastic underwater. The red, of course, comes from iron oxide (rust). What I'm wondering is, would that be dangerous to the shrimp? I've seen it used in aquariums before, but never with an invertebrate. I know shrimp are incredibly sensitive to copper, but I'm not sure if they're A.) terribly sensitive to iron, and B.) the iron would necessarily leach out into the water. I know for a fact the rocks are sandstone, if that makes a difference.

What do you guys think? I would like to use it if I could.

OOO that's like 40 mins from where I live! That would be cool to have some red rock in my tank... I'm interested to see what people say.

I have been using Iron Pyrite in all my tanks for the past 5 years. I read along time ago that it is a good idea to put in a nail or two under your substrate because it is great for plants and over all health or your aquarium. I have shrimp in all but one tank and never have I had a problem. The pyrite goes red and gives a really nice look to the bottom of the tank. Most liquid ferts have iron in them. Go ahead in my opinion and enjoy.

It's 40 minutes from where I live, too! Which is Flagstaff, by the way. :P

@newtchaplin

Thank you! I'm going to put a piece in there, then. I won't be too upset if things go wrong, but I -have- pretty extensively fertilized the tank before, back when I was first trying to establish the plants for them, and I never had any die-offs. I'll update this if anything bad happens.

Awesome! Then I'm assuming you know about AquaTera, our LFS. They're closed for the next week, but they're supposed to be having an extra splendid grand opening on the 31st, so mark your calendar. :P


Oh guys, I also picked up some wood from the area-- it was an entire dead bush of some sort, very fibrous looking. It wasn't technically drift wood, but it was very dead, and very uprooted from the ground, set near the shore of the creek. I've soaked it until tannins no longer remain, bleached it a ton, vingegar'd it a ton, and washed and scrubbed all the obvious bark off. However, it's very soft when wet, and it's one of those woods where it's kind of all homogenous throughout-- I can't necessarily tell if more bark needs to come off, or if it's all just fairly porous and soft. Do you think it would be safe for aquariums?

I used to keep a small piece of iron pipe in my tank that would slowly rust. The plants seemed to love it. At the time I wasn't measuring my iron or other water parameters so I can't tell you exactly what it was putting into the water. I would guess that the rocks would be similar, I think they'd probably be ok, but without knowing exactly what is getting put into the water I can't say for sure. You could put it into a bucket for a while and test the water?
