Ohko Stone (Dragon Stone)
This is one of the most popular rocks for aquascaping. These hardscape rocks were made popular by Takashi Amano when he brought the Iwagumi style of aquascape into the hobby.
They have many ridges, grooves and crevices, making it popular for those with shrimp in their aquascape tanks.
Dragon stone will not affect your water's pH or softness/hardness, etc. as they are pH neutral rocks.
Stones are sold in increments of 5 lbs, 10 lbs & 15 lbs.
