Transform Your Aquarium with Midnight Pearl River Gravel
- Pebble Size: 2-4mm
- Smooth and Naturally Round
- Minimal Effect on Water Chemistry
Midnight Pearl river gravel has a 2-4mm pebble size (perfect for planted tanks), which allows for a massive surface area for the growth of beneficial bacteria colonies. It's naturally tumbled and smooth from thousands of years of exposure to rivers in the pure alpine river of New Zealand.
Midnight Pearl has a base of black pebbles with various shades of brown, gold, and grey pebbles mixed with hints of jasper and green pebbles to give a unique dark richness to the color.
