Hello
I bought a 180l freshwater tank about 10 weeks ago which I change 30% each week. I have it planted and have about 20 small fish mainly tetra and mollies.
However when I do weekly tests my water is always carbonate hard and I am not quite sure how to fix this. My fish shop told me to use my spare utility tap water and not to my house water as I run this through a salt tablet system to soften it but the result is as suspected High and Hard Carbonate.
My question is, is it really unsafe to use my treated water or do I use other chemicals.
Thank you in advance
