    Product details ?Natural Purifier? Clam Shells - For Water Quality Stabilization and Mineral Supplementation

    We deliver natural clam shells from Ibaraki Prefecture, perfectly suited for aquariums and aquaponics.

    These are not just decorative or craft items, but natural multi-functional aquarium materials packed with scientific benefits. ?

    ? Product Details ?
    Boiled, desalted, and sun-dried [Natural Clam Shells from Ibaraki Prefecture]
    ?? Medium size (approx. 8cm) - 4 pieces

    Great value when purchased in sets!
    Available from 1 piece.
    ● Extra Large (10cm+) - ¥200: Overwhelming presence! Crushed, they are highly effective.
    ● Large (approx. 9cm) - ¥150: Good presence, though not as large as extra large.
    ● Medium (approx. 8cm) - ¥120: A convenient size for easy combination.
    ● Small A (approx. 7cm) - ¥80
    ● Small B (5-6cm) - ¥60: Fun for creating hiding places by combining with lava rocks or filter media, or by stacking a few.
    ● Striped Ark Shell - ¥120: The numerous radial ribs create grooves, increasing surface area and making it easier for bacteria to colonize.
    ● Oyster Shell - ¥200: Layered like mille-feuille, and the countless holes (porous) formed by years of tumbling in the sea make it an excellent habitat for bacteria (supermarket oysters do not have these porous holes).

    Additional items can be purchased individually (usually sold in sets) so please comment.

    ? Amazing Effects of Clam Shells ?

    ? Stable Water Quality (pH) Maintenance
    Acts as a pH buffer to prevent aquarium water from becoming acidic, maintaining the neutral to slightly alkaline conditions favored by medaka and shrimp.

    ? Rich Mineral Supplementation
    Gradually releases calcium and magnesium, supporting the health of aquatic life and plant growth!
    Also effective in preventing molting problems in shrimp.

    ? Powerful Biological Filtration (Bacterial Habitat)
    The uneven surface of the shells provides an ideal breeding ground for nitrifying bacteria.

    ? Great for Microorganism Cultivation ?
    Crushed and added to culture containers, it suppresses rapid spoilage (acidification) during the cultivation of rotifers and daphnia, reducing the risk of mass death and promoting explosive growth.
    Dissolved calcium helps cultivate strong individuals.

    ? Quality Assurance ?
    Carefully washed, boiled, and sun-dried, so you can use them with peace of mind as soon as they arrive. ?
