Burgundy lava rock, 3/4 inch

Burgundy lava rock, 3/4 inch, washed and screened and bagged by weight. The larger reddish pieces create a visible irregular texture. Choose a 1 lb or 5 lb bag knowing that individual outlines and piece counts vary within the nominal grade.

Start a hardscape plan with clear movement and cleaning routes. A conspicuous stone surface should not block an equipment intake or create an inaccessible pocket behind the glass. Low supported arrangements are easier to inspect than a tall loose pile that looks secure only from the front.

Check actual edges and gaps before animals use the space. The material's appearance cannot tell you whether a particular fish might mouth a fragment or catch itself between pieces. Match the physical layout to the actual animals at adult size rather than reading a universal compatibility promise into a product name.

Burgundy color does not establish a specific mineral composition, absence of treatment, or a predictable influence on water. The relevant chemistry is awaiting confirmation. We do not describe the material as inert, reef-safe, or a source of plant nutrients without supporting evidence for the supplied batch.

If you are considering contained filter media, check allowable material and maximum loading with the equipment maker. Retain fragments, preserve service access, and manage solids. Dry new stone is not an established biological filter, regardless of how open its texture appears.

Rinse off loose handling fines before appropriate use and inspect the cleaned sample again. Use the calculator as an approximate volume-to-weight tool, then compare merchandise and shipping together. Representative dry and wet imagery is there for visual comparison until real product photographs are supplied; it does not identify exact pieces or certify their chemistry.
