About this item
- 🧪 MINERAL BLOCK THAT WORKS ON FIRST CONTACT: Fizzes on contact with water, neutralising built-up acidity for a cleaner, fresher turtle tank. Unlike calcium powder for tortoise feeding, no daily mixing — your pet accesses calcium in its habitat.
- 🐢 1 BLOCK PER 15 LITRES — REPLACE EVERY ~7 DAYS: Recommended dose is 1 piece per 15 litres of water. Each block lasts around 7 days, often longer with young turtles. Replace once fully dissolved and change the water regularly for best conditions.
- 🌿 100% NATURAL FORMULA, SAFE FOR ALL AGES: Calcium min. 33% + Vitamin B1, with no artificial additives or colourants. Safe for hatchlings, juveniles and adults. Compatible with standard aquarium filters and other AF tortoise enclosure accessories.
- 🪨 CUTTLEFISH BONE FOR TORTOISE — THE AQUATIC ALTERNATIVE: Cuttlefish bone suits land tortoises that nibble it directly, but it does not dissolve in water. The AF block is formulated to release calcium in aquatic habitats or in a humid terrarium.
- 📦 3 PACK SIZES + AF PREMIUM RANGE QR: Packs of 4, 8 or 15 pieces to match your tank size and routine. Ideal mineral support for any water turtle or tortoise owner — also handy at tortoise bath time. Scan the QR for Complete Menus and Snacks.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
