With colors ranging from dark red to maroon, and from green to blue and black, it adds a unique and beautiful touch to any aquascape.
The colored stones of Lake McDonald owe their colors to the iron content in sedimentary pebble rocks and the degree of its oxidation. The rocks were formed for millions of years under different conditions, resulting in the beautiful colors seen today. The lake rocks were then ground into small colored pebbles by giant ice blocks during the Ice Age, which were then brought into the valley by streams of meltwater.
McDonald Lake boulder is available in mix sizes from 10 to 30 cms, and it can be complemented with McDonald Lake Nano Boulders. Some boulders may raise pH and hardness slightly. Regular water changes are enough to keep the hardness under control.
