Whenever I change my water I only use Tetra brand Aquasafe that removes chlorine and copper. I usually fill an old 2 liter soda bottle (it's been cleaned throughoutly and was a long time ago) I always use the same one so I know it's clean.
For every 2 liter bottle of water I put in 4 drops of aquasafe. Is this okay? I probably would have a hard time getting other conditioner but if I could convince my dad it's urgent than maybe I can get some more if I absolutely NEED more conditioners. I use tap water that's been tested and I know the levels in it are somewhat ideal. (not really any ammonia, a bit of copper and chlorine but conditioner removes that, PH 7.6)
So basically, is it okay for me to continue doing what I've been doing to condition the water?
