So Ive been curious about this. I have a water softener that I use in the house and have been using the water that goes through the softener for my water for my vieja species. Is this alright or should I just bypass it and use the normal tap water that I'd quite a lot harder for these fish. The general hardness that comes from the water softener reads 0 and a pH around 7. I know these fish prefer harder water but can they adapt just fine to softer water? The water softener wasn't working up until about a week and a half ago so I was using just the normal hard water from the tap but slowly acclimated them to the soft water now since it was fixed. So should I bypass it and just use the harder star or is the water from the softener just fine to use. Thanks
