Mags Posted December 17, 2009 Report Share Posted December 17, 2009 OH is thinking of getting a tropical fish tank but we have a water softener on our hot tap, not on the cold. Would the salt content be a problem? Need answers fairly quickly please Link to comment Share on other sites More sharing options...
Ruthi (borrowadog) Posted December 17, 2009 Report Share Posted December 17, 2009 Yes. The salt will kill most tropical fish. There are a very few varieties that are OK in slightly salty water, but the amount of salt in your tap water will not be controllable enough to keep them. You need to use the water from your cold tap, and warm it up to the same temperature as the tank with kettle water. I used to find that one kettle full of water warmed up a bucket of water(but you need to test that!). You will also need to either stand it for 24 hours first to let the chlorine escape, or use special dechlorinator. The kind of fish that thrive in your local tap water will vary according to the area you live in. Your local fish shop will be able to advise you on that.
