Copper in the Water

I believe I may have copper in my tap water. I have yet to be able to keep a snail for more than two weeks (even my population of pond snails is in rough shape and its not from lack of food) and my four ghost shrimp have all but disappeared (there was one left as of this morning).

My ammonia and nitrites are at zero and have been steady for weeks ( at least 6 weeks anyway). Nitrates are always under 20 and I do weekly water changes on both tanks.

I have well water that has about 5 degrees general hardness and no nitrates. I do use a chlorine/metal remover conditioner with water changes just as a precaution (figured it couldn't hurt but maybe it does) but add nothing else to the water. Ph in my 10g planted is steady at 7.2 and in the 8g hex with driftwood it is at about 6.8 I think.

I suspect copper because we often have problems with the pipes in the house springing pinhole leaks. I figure if the water is eating away at the pipes to cause leaks, odds are some of that copper is leaching into the water coming out of the tap. It (or some other metal) is the only thing I can think of that is killing off my invertebrates like flies.

My fish seem okay although the redness qround the gills that showed up on my danios during cycling has never gone away (although its lessened) despite the absence of ammonia.

My question is, what can I do (on a budget) to clean my water up. Short term I guess I can mix distilled water with tap water to reduce any metals and retain minerals but is there a long term solution besides R/O? Even though they're small tanks (and I'm only in this house for another 6 months or so) I'd hate to have to keep buying distilled water. Will something like a Brita remove metals?
 
According to most publications, RO or RODI is the only effective filtration for removing copper. What you may want to try is running the cold water for several minutes before collecting it for use in your tank--letit get as cold as it can. You may want to heat this water before using it in your tank--depends on how much you're replacing and what fish you have in the tank. This flushing gives you water that has not been sitting in your pipes for an extended time period, meaning no copper will have leached into it.

There are copper test kits available--I've never used one so do not know how accurate they may be.

http://www.ianr.unl.edu/pubs/water/g1360.htm has some very good information about copper in the water--and may help you determine if it is likely that your pipes are corroding and in need of replacement.
 
If the problem is with your pipes in the house and not those coming in from the water Co., then it may be possible there is already or that you add a faucet right where the water enters your home. This would allow you to hook up a hose and bypass your pipes.
 
OG, I didn't even really think about running the water. That would probably help a lot. I age my water in five gallon buckets for a week before I add it to the tanks so the temp isn't a problem.

TwoTank, The spot where the well plumbing enters the house system is inconvenient to access so thats out. Thanks though
 
I switched to using my Brita to filter my tank water, and I have not a lost a shrimp since I bought them a week ago. This is a new record for me! According to the packaging and accompanying lab reports, Britas do remove copper, although I imagine I will change the filter more often now. My fish get more use out of the filter than me as it is, I do not know what I am going to do when I get my 10 gallon, oy.
