Has anyone tried adding bottled water to their tank (10 gallon) for temporary Nitrate reduction? My problem is that I'm done cycling (still adding a couple of drops of ammonia each day when it drops to 0 ppm), but no shrimp (they're coming in 2 days). My Nitrate always runs around 10-20 ppm. Even after I do a 50% water change, it doesn't really drop because my tap has 5 ppm. The bottled water is at 0 ppm. I'm sure once the shrimp are in there and I stop adding Ammonia, the nitrate won't be that much of a problem.
