My tap water is fairly hard (an 8 [143 ppm
for both] dGH and dKH
I think). Anyway, it took several drops to make the color change and the carbonate and general hardness were very close to each other. I think this is good water to start with for malawi cichlids, isn't it? The pH has always tested around 7.6 - 7.8. I've tested it with several electronic instruments, strip tests, and reagent kits.
Do I need to add anything to increase the pH and hardness for malawis or is it basic and hard enough?
