Hi Guys,

Anyone have one of these and use the water for their fish?? any comments.....

Would like to hear all comments on it...

P.S. The water before the softener is really hard!!

I believe most home water softeners do not work by either reverse osmosis or deionization, although some do. Most home softeners are mainly used to remove calcium and magnesium by replacing them with either potassium or sodium or a combination of the two. This allows large-scale water treatment without delay or costly waste-water. Is the water produced suitable for home aquaria? Certainly, although there is no "gain" in lower general hardness. What brand is your water softener? I'd double check and make sure it removes heavy metals like lead and iron (it probably does).

Most home water softeners soften water by swapping ions of calcium and magnesium for sodium or potassium ions (depending on what resin is used). If you have a GH test kit, the resulting water should read "0" but what you don't see is that the TDS (total dissolved solids) goes way up. That's because 2 ions of Na+ or K+ are swapped for every Ca+ or Mg+ ion. A softwater fish lives in water that is both low in GH and TDS. So having a low GH from a water softener really does nothing to replicate their natural water parameters.

Will fish the fish live? Although not ideal, I've known hobbyists who are able to keep fish in softened water. Small fish might have problems with skeletal development due to low calcium levels though.

Thanks Guys...

I am using 1/2 RO water with 1/2 tap (unsoftened) at the moment to lower the hardness and keep the TDS at a min. Seems to be working...things are still breeding!
