Recreate the cold, natural beauty of Lake McDonald in your aquarium with the Glacier River Kit. Named after the famous glacially-carved lake in Montana's Glacier National Park, this kit captures the remarkable multicolored character of McDonald Lake's legendary painted pebbles — one of nature's most extraordinary geological spectacles.

The McDonald Lake Boulder is the centrepiece of this kit — a rare natural mix of stones from different origins whose vivid colors ranging from dark red to maroon, green, blue, and black owe their stunning palette to iron content and oxidation processes over millions of years. The kit includes a full range of McDonald Lake Boulder sizes from XL down to small, alongside a 2 kg bag of McDonald Lake Nano Rocks for foreground detail. The dark tones of the Artist Dark plant substrate — a 5 kg nutrient-rich growing medium — provide depth and contrast beneath the colorful stones, while the Glacier Biotope Beds bring authentic natural fine substrate material.

The result is a vivid, geologically rich riverbed that feels genuinely wild — perfect for cold-water biotopes, river-inspired scapes, or any layout that seeks extraordinary multicolored character.
