Haku Mountain Rock Mount Haku is one of Japans 3 holy mountains. There are 2 main trails leading to the summit which is well worth the hike ! The Haku mountain rock is a beautiful blend of natural colours , in the main it is white / grey and lilac with some other colours interspersed in some pieces . Most pieces have a lot of quartz within the rock as well which gives it that ultra premium look and feel . We would suggest using 10KG per 50L. For example, for a 100L tank use 20KG.
