A ph reading above 7 is considered alkaline. For a tanganyika tank 8.2-8.3 is ideal. Hardness refers to the amount of dissolved salts in water, there is GH, which is calcium and magnesium, and KH, which is carbonate/bicarbonate. The first thing to do is get ph,GH, and KH test kits, then you can determine what, if anything needs to be done to your water.
