Q: How much salt should go in a fresh water tank?

May 8, 2008 | By Karen A. | 1 answer | Expired: 2815 days ago

I have several freshwater tropical tanks and have been reading that salt should be added in small amounts to the water. This is confusing to me, since I thought fresh water tanks were the absence of salt. I have Bettas and Cichlids in 3 tanks, Danos in the other. Do all of the tanks need salt and how do I figure out how much? Will it hurt my fish if not added?

Hi Karen,I just want to say that I've kept tropical tanks all of my life ,and the only time that salt was ever involved was when I was treating someone for an illness or a Parasite.
Salt is a very tricky product once you begin using it, because it doesn't dissipate from the water.The only way to reduce amount of salt would be to do extremely large water changes,so by adding a little here-a little there,you could actually do more harm than good.
Mollies were always one of those fish that could live in either brackish or fresh water,but the ones that come from Pet Shops have normally been raised in fresh.
As for your Chiclids,what kind are they? I've known a lot of people keep them in fresh water with no problem. I also know quite a few that use Chiclid Buffers. AFricans Chiclids for example, need hard water and some people use cichlid buffers(cihclid salts) These sorts of Buffers balance out your calcium, magnesium, potassium and trace elements & help to bring the ph up and make their water harder.
Check out the Seachem site.They sell all kind of buffers for different types of cichlids and may have further help for you.
