Water Chemistry

[Damascus]

Hey MFK,

So recently I replaced my water softner in my house. There was enough GH getting by as my old softner let some through at about 5 degrees.

I never even thought about it with my new softner. I have had my fish in water with 0 Gh for the last few months. I just put in a bypass value and I am wondering what the best way to start adding gh back into the water for my fish.

During a water change, I will probably have to switch periodically between softened water and my well water due to the species that I keep not appreciating how hard my water naturally is.

Is this OK to do? My well water is about 16 degrees, and I'd like to keep my tank at 4 degrees. So if I just add a 1/4 of the tank volume at the end of the well water, it'll mix and bring the gh level to my desired 4.

Any advice here?

Hello; As with any change in water the simpler trick is to do a chance gradually. I think of these things the same way as bringing new fish home from a fish shop. I do not know what the difference might be between my water and the shop water. I do an acclimation. Should be the same for what you are doing. It can be a sudden change which is hard on fish.
Good luck
