Coarse, free-flowing blue crystal — the classic form for pond and spray applications.
Copper Sulphate Crystal is copper sulphate pentahydrate processed and sized into coarse, irregular blue crystal chunks. Its larger particle size means slower dissolution than powder, low dust generation, and easy manual dosing — which is why it remains the preferred form for pond treatment, Bordeaux mixture preparation and general agricultural use.
Because the crystal form dissolves gradually, it is well suited to applications where a controlled release of copper ions is desirable, such as algae control in open water bodies and slow-dissolving stock solutions.
