I am seeing conflicting information regarding kh and gh and I would like some advice from people who have a good understanding of this subject.
My water out the tap has a kh of 2, and a gh of 4, and a ph of 7.5.
My first question is concerning mainly the kh, I read that ph will fluctuate at a kh of 2 or lower from some sources, but I am also reading that this only really happens from people who use co2, so will My ph be an issue with this kh?
My second question is regarding whether my water is considered soft or hard?
I do not plan to use co2, I plan to keep south American dwarf cichlids and tetras.
Also the tank has been cycling about 2 weeks, tank is already heavily planted, and I have been dosing 1ppm of ammonia and so far ph has remained stable at 7.5, tank has some seriyu stones as well and I have heard those raise kh.
All advice is appreciated! 🙂
