    I think I should buy more sand as well- If I ever get another tank. I like the idea of quartz, my only worry is if it changes the water hardness or anything.

    Quartz is inert.

    http://www.quartzpage.de/gen_chem.html
    At room temperatures quartz is practically insoluble in water. Tap water is usually almost saturated with dissolved silica (with respect to quartz), and the dissolution process is very slow, so there is no need to worry about quartz crystals being damaged by repeated cleaning.Nevertheless the dissolution of silica in bedrock and soils plays an important role in hot humid climates. The formation of laterite soils is linked to silica being gradually washed out of the surface layers and an enrichment of compounds that - at least under those climate conditions - are less soluble in water, like iron and aluminum oxides.
    At temperatures above 100C and high pressures the solubility of quartz increases quickly. At 300C it is between 700 and 1200 mg/l, depending on the pressure.

    Also is the main component in "sand". There can be other fine rock and mineral grains depending on where the "sand" comes from, but it is mostly SiO2 which is quartz.
