Noddy65 Posted January 30, 2012 Share Posted January 30, 2012 A relatively small amount of salt in the water can inhibit nitrite uptake at the gills...about 0.1% is sufficient (1 cup/100 gallons). Link to comment Share on other sites More sharing options...
Ged Posted January 30, 2012 Share Posted January 30, 2012 I had read this in a number of articles but they did not provide definitive salt concentrations. Have you read something recently that provide evidence of the affect of salt on nitrite blood absorption rates? Link to comment Share on other sites More sharing options...
mattrox Posted January 30, 2012 Share Posted January 30, 2012 The only thing I have been told it it is the Chloride ion that interferes. I am yet to read up on it. Link to comment Share on other sites More sharing options...

pseudotrop Posted January 31, 2012 Share Posted January 31, 2012 Chloride competes with the nitrite for uptake in the gills, apparently freshwater fish concentrate nitrite this way.This article provides a dose of 1mg/L of chloride, raising the LC50 by a fair bit.http://cires.colorado.edu/limnology/pubs/pdfs/Pub079.pdf Link to comment Share on other sites More sharing options...

cyber_crimes Posted January 31, 2012 Share Posted January 31, 2012 I was at Kellyville pets not long ago and noticed a Blue Tang in a freshwater tank.When I asked about it I was told they give their marine fish a fresh water bath much like the old "freshwater species in a saltwater bath" for desease remedy etc...

mattrox Posted January 31, 2012 Share Posted January 31, 2012 This is useful, rather than a scatter gun disease remedy, nitrite can be easily detected and the 1mg/L Chloride is a precise dose, with measureable benefits.Treating a disease or condition with a correct diagnosis and precise treatment usually achieves better outcomes than a scatter gun or broad-spectrum approach.Not saying that those treatments aren't useful......

mattrox Posted February 3, 2012 Share Posted February 3, 2012 That is a really interesting article. The way I read it is that 1ppm Choride mitigates 0.37 ppm of nitrite being taken up by the gills. This nitrite affects each species differently, but low levels effect sensitive species. Other species can tolerate higher levels. Erring on the side of caution never hurts.So in effect if a nitrite test is positive, a pwc will bring down the levels, there will still be nitrite present and it will build up again until the next pwc. Dosing the level of chloride required (before pwc) will help protect the fish.To work out the amount of salt required:amount of salt (NaCl) needed in g = Nitrite level (ppm) / 0.37 * 0.00165 * tank volume (Litres)Someone check my maths.... but I think that should work. And would be very useful during a filter crash. Link to comment Share on other sites More sharing options...
Ducksta Posted February 3, 2012 Share Posted February 3, 2012 So add salt (for the chloride), after you've dechlorinated the tap water?Would any 'dechlorinator' still active during a water change be effectively removing the Cl gained from adding salt or does the different state help it hold?

mattrox Posted February 3, 2012 Share Posted February 3, 2012 The dechlorinator turns chlorine (hypochlorite ion) into the chloride anyway. In effect the chlorine in tap water is helping the process once it has been "de-chlorinated" by adding more chloride ions. Link to comment Share on other sites More sharing options...
