Black Star Lava Rock

Stones should be cleaned prior to use. Do NOT boil any stone hardscape. Click here to shop all hardscape! Black Star Lava Rock is a unique variation of the classic aquascaping stone, Black Lava Rock. Black Star Lava Rock features a uniquely rounded shape that is much smoother than other Lava Rock varieties. This characteristic makes the round aquarium stones great for scaping in tanks that contain livestock with sensitive fins such as Fancy Goldfish, Betta Fish and more. Black Star Lava Rock still sports a porous texture that will support a variety of aquarium plants that are commonly grown on aquarium hardscape. Black Star Lava Rock works great as a base stone with driftwood or alone. We recommend wrapping them with aquatic mosses for additional greenery wherever desired! Another benefit of having Black Star Lava Rock in a tank is its ideal habitat for the colonization of beneficial bacteria resulting in a healthier aquarium environment. The best thing about Black Star Lava Rock is that due to its relatively lightweight, you'll get more volume per pound. How many pounds do I need? We advise 2 x Tank volume in gallons = Total amount of pounds required TIP: Take advantage of Lava Stone's porous texture! It provides a perfect surface for delicate aquarium mosses to grow on. We like Mini Pellia and Fissidens Fontanus!
